SIX 

SIMPLE STEPS 

1 Move the flashing pen around 
on the screen using the four 
arrow keys. 

2. Use it to draw or adjust items 
of background scenery. 

3. Scroll the screen to another 
position and continue drawing. 
The area of scenery is unlimited! 

4. Use the pen to draw your 
animated figures. Each one can 
be up to one quarter screen size 

5. Move the figures over your 
background scenery using the 
four arrow keys. The screen will 
follow the figure you're currently 
moving. 

6. Now sit back and watch your 
first movie. Movie Maker will 
playback all of the movements 
from step 5 above.

Movie Maker to playback your movies 
at an incredible speed of 22 frames 
per second. And also enables a single 
movie to be over 20 minutes in length. 


Some Movie Maker facts 

Text can be used in the form of subtitles or as scrolling bubble 
messages which appear above the figure that's speaking. There is

Hear SPEECH! for yourself in the loader 
programs of REPTON 2 and CITADEL. 

Every copy of SPEECH! comes 
complete with 5 programs: 

SPEECH! — the 7K program 
DEMO — shows off all the features 

SPELL — a simple educational 
program 


A T last, speech synthesis at a price you 
can afford. SPEECH! works entirely in 
software, taking up only 7K of RAM: no 
hardware whatsoever is required. Unlike 
other systems, SPEECH! has an unlimited 
vocabulary: it will say anything you want 
it to, and is simplicity itself to use. Simply 
type in: 'SAY I am a talking computer, as 
easy to use as 1 2 3 . . . and the computer 
speaks.

Adding a question mark to the end of a 
word pushes the pitch up ('SAY How are 
you?) and a full stop pushes it down ('SAY I 
am really unhappy.) You can even 
change the overall pitch by using the 
‘"PITCH” command. 


SAYFILE - says WORDWISE, VIEW 
files etc 

RELOCATE - moves SPEECH! around 
in memory, onto 
Sideways RAM, etc 


SPEECH! has a built-in parser which 

translates English words into 'phonemes’ 

or speech particles. There are 45 different £ 

phonemes, and 8 different pitch settings 

for vowel sounds. These phonemes can 

be used directly by using the '"SPEAK” 

command (e.g. 'SPEAK HEH4LOW4), so 

stress or intonation can easily be added 

wherever desired. You can even say 

foreign languages. 



Applications in: 

• games •business 

• education • utilities 

Previously, to get this quality of 
speech you would have had to 
pay at least £30. SPEECH! costs 
only £9.95 on cassette or £11.95 
on disc

The shape of 
memory to come 


Cumana - the company which 
made its name selling disc drives 
for BBC micros - has unveiled a 
revolutionary memory technique: 
a chip mounted on a credit card. 

The Astron card, with inexpen- 
sive adaptors, will be in the shops 
this month, first of all in Dixons 
with a game for the Commodore 
64. Initial products will be equiva- 
lent to 16k ROM chips, but RAM 
and EPROM versions are on the 
way, as well as a 128k product. 

Price of the card plus interface 
will be about £24, with the cards 
themselves costing £5 - expected 
to come down to around £3 by 
December. A battery-backed ver- 
sion is under development. 

Cumana is distributing the sys- 
tem for Japanese company Astar 
International under an exclusive 
European licence. General Instru- 
ments is pushing it in the US. 

Astar has repackaged conven- 
tional chips by surface mounting 
them on a sheet of plastic. This is

A 16k chip is embedded in this card shown actual size 


already done in Acorn’s cartridge 
software for the Electron and 
Master but it is the portability of 
Astar’s system which is new. 

The first interest in the UK has 
been from security companies, 
and the army. The Royal Engi- 
neers have been using the cards in 
the Beeb’s serial cartridge slot on 
the left of the keyboard which is 
normally covered up. 

Cumana’s managing director 


Olivetti to compete with Acorn in schools 


Olivetti has launched an IBM PC 
compatible micro in competition 
with Acorn’s Master 512 for sale 
to schools. 

The M19 will cost about £1400 
and be available in May - three 
months before the Master 512 
priced at around £900. Both ma- 
chines will go into secondary 
schools to train pupils in business 
software - which is where the 
Olivetti machine has the edge as it 
has a much higher degree of IBM 
compatibility. 

An Acorn spokesperson ex- 


plained that it was a historical 
situation which was unlikely to 
happen again. In fact Acorn joint 
founder Hermann Hauser has just 
signed on with Olivetti as director 
of advanced research and 
development. 

At the launch of the Ml 9 micro, 
which uses the 8088 processor 
running PC-DOS and will run 
standard IBM software such as 
Lotus 123 , Olivetti talked about 
porting BBC micro educational 
software on to the machine. How- 
ever, Acorn was unsure as to its 


involvement in this. Both compa- 
nies put a brave face on the pros- 
pect of competing with each oth- 
er. An Olivetti spokesperson told 
Acorn User. ‘Obviously there is an 
overlap, but we’d rather see that 
than a gap’. 

Acorn echoed the sentiment: 
‘We’d rather sell schools an Ml 9 
than see them go out and buy 
anything else’. 

Acorn will ‘make the Ml 9 
available’, and it might well carry 
an Acorn badge, although a firm 
decision had vet to be taken. 


Don Bolton was extremely confi- 
dent about the new system: ‘We 
see it being very, very big and 
growing very fast.’ He also saw it 
having revolutionary possibilities 
for computer hardware, even do- 
ing away with traditional RAM 
and ROM in micros. 

The army, he said, was even 
looking into replacing the con- 
ventional ‘dog tags’ with a card, 
and the REME had set aside £T 
million to develop the system. 

At the launch last month Cuma- 
na was showing the cards working 
with BBC micros driving Alfred 
robots, and Superior Software’s 
Speech software. Acorn was there 
with the Communicator, and 
talked about the possibilities of 
putting the card interface on the 
side of the machine. 

Other big names mentioned in 
connection with the card were 
Sinclair - which is working on a 
portable micro called ‘Pandora’ - 
and British Telecom. 

Acorn has taken one of the 100- 
or-so development systems that 
have gone out, although had not 
had time to design the hardware.

THE MAN FROM 


V.V.8.I.K. 


Rats. All excited I was. When the 
Master was launched they said 
that the 512 version was based on 
the Motorola 68000 processor, 
didn’t they? I know I didn’t imag- 
ine it. Dancing in the streets. 
Jubilation on a cosmic scale. 

However, back at the Acorn 
Strategic Offence Initiative head- 
quarters, dark plans were afoot to 
bring the Great British Public 
back under the yoke. ‘Now zat ve 
haff ze enemy veil and truly 
drunk, ve go for ze killer blow. Ze 
next lot of adferts vill announce 
zat ze processor vill be ze 80186! 
Ha, Ha.’ Same as the IBM PC. 
Argh! It’s like being told that we 
didn’t win at Waterloo after all. 

I was at the annual masque ball 
of the regional chapter of the 
Ripoff Artists last week. As a 
guest/observer of course. It was 
interesting watching these fellows 
attempting to sell each other life 
insurance while nicking every- 
thing that wasn’t nailed down. 
Discs, ROMs and tapes were 
moving around the room at flank 
speed. Similar to ‘pass the parcel’ 
except that the passing was invol- 
untary. They seemed to enjoy the 
dare-devil thrills of sleight of hand 
more than the programs. 

Still, it’s not surprising when 
you consider the state of software. 
How many more ways are there of 
simulating the destruction of 
some poor alien who’s probably 
got a family, mortgage worries 
and athlete’s foot? The greatest 
innovation is in protection sys- 
tems. Certainly the shadowy char- 
acters at the ball appeared happiest 
when telling how long it had 
taken to crack some elaborate 
piece of code. 

I suppose it’s like doing cross- 
word puzzles really. I don’t like 
them either. 



NEWS 


The new body set up to develop 
computer education in the UK, 
the Microelectronics Support 
Unit, has no director, no staff and 
no premises. The MSU was due to 
take over on April 1 from the 
Microelectronics Education Pro- 
gramme (MEP). Yet by that date 
the Department of Education 
(DES) had only appointed a board 
of 11 advisors and a chairman, 
Mike Nichol. 

Without a director, the MSU 
cannot implement any policies. 
Without premises or staff the unit 
is unable to develop materials or 
provide practical advice to local 
education authorities. 

Acorn User spoke to Mr Nichol 


just two weeks before his unit was 
due to take over from the MEP. 

He was confident that by the 
autumn the MSU would be fulfill- 
ing the role envisaged by Sir Keith 
Joseph, the education secretary - a 
small central support and advisory 
body. £3 million has been set aside 
for the MSU in the financial year 
1985/6, as against the MEP’s £4.5 
million in 1984/85. 

A former MEP employee said: 
‘It took the MEP five years to 
achieve its innovative position. 
The DES has undone all that 
work and it could be another five 
before the MSU is truly function- 
ing in the way Sir Keith Joseph 
would like.’

The ribbon costs £12.50 and is

Computers, 3 Schofields Way, 
Bloxham, Banbury, Oxon. 


Musical theory 

Nebulae Micro Software has pro- 
duced a music package for the 
Beeb which teaches the elements 
of counterpoint theory. 

The software costs £22.95 on 
disc, and versions for Amcom or 
Econet networks cost £35.

New Star spotted 

The latest addition to the Star range of printers is the 
NL-10. This dot-matrix printer costs £278, with a 
parallel interface, and as the name suggests is capable 
of Near Letter Quality (NLQ) printing at 30 charac- 
ters per second. 

In draft mode, the NL-10 runs at 120 cps. Other 
features include user-defined characters, an italic font 
and a headline mode where text is printed at double or 
quadruple height.

Econet developed for businesses 


Plans are afoot to take Acorn’s 
Pxonet local area networking sys- 
tem out of its present educational 
niche and into the fast-growing 
business world. 

SJ Research is developing a 
range of intelligent Econet inter- 
faces for business machines, in- 
cluding the IBM PC which has 
half the business market. 

Three interfaces are being 
planned, for each of the major 
computer connection bus stan- 
dards, including SCSI, allowing 


the Apple Macintosh to hook up 
to Econet; the VME bus, as used 
on Torch’s Triple X range; and 
the IBM PC bus. 

SJ Research is working with 
Torch, Acorn and several large 
users of Econet to define ‘what 
can and cannot be done with 
Econet and business computers’, 
according to Kim Spence-Jones, 
SJ Research’s technical director. 

Other Econet suppliers prefer 
to remain anonymous because, ac- 
cording to Spence-Jones, ‘there’s 


still a lot of stigma attached to 
Econet; a feeling that it is a toy 
network for schools.* 

SJ Research is to release a more 
sophisticated Econet file server, 
MDFS, which will cost £1200 and 
will support four disc drives, a 
hard disc and a tape back-up. 

A top-of-the-range HDFS file 
server with 80 MByte hard disc, 
tape back-up and triple processors 
costs £7200. Other new SJ prod- 
ucts include a viewdata simulator 
for Econet and a menu system.

THE VERDICT 

' Opus have got a winner on their 
hands. It you are looking for a 
disc upgrade you can’t go tar 
wrong by buying a Challenger, 
even it you already have a single 
drive this would certainly be a 
sensible upgrade path. This cer- 
tainly gets my vote as best buy ot 
the year." 

A & B COMPUTING - JANUARY 1986 

RAM DISC 
PERFORMANCE 

' 'Here is the piece de resistance of 
the whole system - a 256 K RAM 
disc. I honestly don't know how 
Opus can do it for the price. 

Using the RAM disc is a real 
dream with disc based applica- 
tions. Getting back to the actual 
performance of Spellcheck II, 
with the dictionary disc set up in 
the RAM disc, the result is 
amazing. When in automatic 
checking mode the text scrolls 
past so fast it is difficult to read. To 
put some figures on the improve- 
ment in speed, I checked a docu- 
ment just over 21 K long, which 
took 5 minutes 56 seconds on 
floppy and only 1 minute 7 
seconds using the RAM disc ’ '

THE VERDICT 

“For the serious user Challenger 
could make file handling far 
easier and a good sight faster to 
use than a standard DFS as well as 
bringing a permanent end to ’is it 
40 or 80 track, single or double 
density?' problems. In addition all 
the workspace used by a standard 
DFS is reclaimed and made avail- 
able to the user by Challenger." 
THE MICRO USER - FEBRUARY 1986 


THE VERDICT 

"At £249.95 inclusive you get the 
RAM disc, double-sided 40/80 track 
drive. Opus DDOS plus manuals 
and leads. Overall very good 
value for money, particularly if 
you are looking for a disc upgrade 
from scratch." 

ACORN USER - FEBRUARY 1986 

RAM DISC 
PERFORMANCE 

“The big deal comes in the 
speed. Being a purely electronic 
device, actions such as reading 
and writing are performed in 
fractions of the time a mechanic- 
ally engineered disc drive takes. 

To prove the point, I ran three 
programs on the RAM disc and 
the same three on the standard 
Opus drive with the following 
results (timings in seconds): 

RAM 

DISC NORMAL 

1 Save 32 K memory 0.34 13.69 

2 BPUT 1 to 1000 1.14 4.71 

3 PRINT/1000 strings 4.64 10.17 

You don't need me to point out 
the huge speed increases.”

RAM DISC 
PERFORMANCE 

"Of course it’s not just a versatile 
disc drive, Opus also provides 
you with 256 K of RAM to play 
with. This RAM thinks it is a disc 
and the DDOS treats it as drive 4. 
If you have the 512 K version you 
get a drive 5 too. The RAM disc 
allocates sectors to files so that 
errors such as 'can’t extend’ are 
eliminated. In other words, it is a 
simple matter to use the RAM disc 
for most of your random access 
files then copy completed files 
from the RAM disc to a floppy 
disc."

School modem 
scheme on-line 


by Bill Penfold 

The Government has increased 
new funds for putting a modem in 
every middle and secondary 
school by 50 per cent because of 
the sheer scale of the response to 
its scheme. 

In less than a week after the 
scheme was unveiled by Informa- 
tion Technology Minister Geof- 
frey Pattie, more than 5000 
schools had snatched up the offer, 
and the overwhelming majority of 
these orders are to put school BBC 
micros on line. Now an astonished 
but delighted Mr Pattie has in- 
creased the original £1 million 
funding to £1.5 million. 

Under the scheme schools have 
been offered free modems plus 
software, with the promise of a 
National Computerised Informa- 
tion Service (NERIS) being estab- 
lished for schools before the end 
of the year. This will initially 
cover the curriculum areas of 
maths, science and geography, 
with other subjects being added. 

Whitehall officials had expected 
some 9000 to 10,000 schools to 
take up the offer, but the enthusi- 


astic reaction meant that within 
days this was revised up to an 
anticipated 12,000. 

The Department of Trade and 
Industry (DTI) expects that just 
about every secondary and middle 
school will have a modem within 
the next few months. 

Two types of modem are being 
supplied - both of which are 
already extensively used in some 
schools - the Tandata 512 and the 
Dacom DSL 21 23 AD, normally 
costing around £200 but which 
the DTI has bulk-purchased for 
£110 each. 


From mighty 
Acorns little 
Beebs grow 

Yes, that’s a real £1 coin behind 
the diminutive BBC micro (left) - 
monitor, copy of Acorn User and 
user guide are all faithfully repro- 
duced at the same 1:10 scale. 

This Lilliputian feat was accom- 
plished by AU reader Peter 
(dements, who has been making 
models as a hobby for seven years. 

The Beeb is cast in resin from a 
mould, and the master took a 
painstaking two weeks to carve 
out of epoxy putty. The mould 
has also been used to cast Beeb 
badges ( AU January). 

The monitor lights up, thanks 
to an internal bulb, but the R evs 
screen is unfortunately static - it’s 
simply a colour transparency of a 
full-size screen shot. 

The user guide and copy of AU 
were reduced photographically 
and the spiral binding is made 
from fuse wire. 

Acornsoft wanted to buy the 
mini micro and its puny 
peripherals but said Peter: ‘It was 
just a one-off and is definitely not 
for sale’. 


Micro adventures

Dolphin is offering BBC micro 
computing as an option in its

Graduate’s Soft Option 


Torch Graduate owners have a 
new company to go to for support 
called Soft Options. 

The Graduate add-on offers 
IBM PC compatibility to Beeb 
owners, and Torch has always 
maintained that because it runs a 
large range of IBM PC software 
there is no need to produce soft- 
ware specifically for the Graduate. 

However, A Sherman, one of 
the Graduate’s designers, thinks 


differently and has set up his own 
company, Soft Options, to pro- 
vide a ‘much-needed’ service for 
Graduate owners. 

Its first release is a £40 utilities 
disc of seven programs, including 
one to convert MS-DOS files to 
Acorn DES format, and a disc 
copier which exploits the Gradu- 
ate’s 1770 disc controller chip.

Cubs Colourful Master 


A corn’s BBC Master Series bring exciting new levels of 
sophistication to a proven family of micro computers. 
Unfortunately, not all monitors on the market can do 
justice to the Master Series' colour display capabilities. 

That’s why more BBC users choose a Microvitec CUB 
colour monitor than any other - because every model in the 
CUB family is a masterpiece of high performance British design. 
The clarity, depth of colour and rock steady image seen on a 
CUB display allows the user to exploit graphics and text to the 
full - just ask for a demonstration of a CUB alongside someone 
else's monitor and you’ll be totally convinced. 

In the meantime, the picture above amply demonstrates 
why a CUB is a delight to the eye in more ways than one.

Instant video digitising for the Beeb 


Wild Vision has produced a real- 
time image processing system for 
the Beeb - the Hawk V8. 

The unit costs £970 and stores 
video images from a monochrome 
camera in the Beeb’s screen mem- 
ory. Direct memory access 
(DMA) means that the screen 
memory is continually updated 
without burdening the processor. 


This is Font one in normal size 
This is Font three in normal size 

This Is Font five In normal size 

This is Font seven in normal size 
This is Font nine in normal size 


Unlike cheaper picture 
digitising systems for the Beeb 
which scan the image, the Hawk 
works in real-time, grabbing the 
image almost instantaneously and 
displaying it in either mode 0 or 
mode 2. 

The system has already been 
used for a medical application - 
studying foot pressure patterns - 


and Wild Vision sees other appli- 
cations as security systems, CAD, 
industrial inspection and scientific 
image analysis. 

Hawk V8 comes as a board, 
which sits inside the Beeb’s case, 
and image processing software. 

Wild Vision, MARI House, 20- 
22 Jesmond Road, Newcastle- 
upon-Tyne NE2 4PQ.

Some of the type styles available in

Clares has released six new pieces 
of software for the BBC micro and

Fontwise P/us improves the ex- 
isting Fontwise printer driver so 
that it now works with View files, 
in addition to Wordwise and 
Wordwise Plus. The program al- 
lows text files to be printed in 12 
type styles on an Epson-compati- 
ble printer. Cost is £20.

128, priced at £40. It will assemble 
65C02 code as well as 6502. 

Another upgrade, Prow Plus en- 
hances the facilities of Clare’s 


Brow toolkit ROM, which has 
been reduced to £20. The new 
version costs £34.50 and has utili- 
ties for discs and memory as well 
as Basic utilities. 

Statewent and Stock Control are 
the two latest additions to the Beta 
Accounts integrated accounting 
suite at £25 each. 

Finally, Clares has put six of its 
best educational programs on one 
disc. Educational Cowpendiuw costs 
£12 - buying them separately 
would set you back £32.

Roma: £4000 
from death 

The life of Roma the tigress is still 
in the balance, with £4000 needed 
before the end of April. 

Acorn employee Martin 
Grantham single-handedly took 
on the mammoth task of raising 
over £20,000 to build an enclo- 
sure at Linton Zoo, Cambridge- 
shire for Roma, who was made 
homeless when Knaresborough 
Zoo closed (AU March). 

Response to his appeal has been 
tremendous, with £17,000 raised 
by early March - with AU readers 
contributing £750-£1000. 

£4000 is still needed, but Mr 
Grantham is confident he will 
raise it. If he can’t, the RSPCA 
will put Roma down.

ger Fund, Midland Bank, 52 St

POST A PROBLEM 


AS a result of pressure from readers, Acorn User now guarantees 
a fast reply service for enquiries. Your answer will be returned 
within 10 working days for just £2 (includes VAT), or your 
money back. 

The idea is simple. Just write out your problem, fill in the 
coupon (right), and send both off to Acorn User with a stamped 
addressed envelope and cheque or postal order for £2. (If you 
want recorded delivery, add the cost of this on. The same goes 
for overseas readers.) Include as much detail as possible and a 
disc or cassette if a program is involved with enough space to 
record any corrected listing. 

We will then answer the problem and return all material 
received - within a guaranteed 10 working days from receipt. If we 
fail to match this promise your cheque or postal order will be re- 
turned with the answered question. If we cannot answer the 
problem, the cheque will be sent back to you. 

If you want a listing debugged, advice on hardware or 
software, or a list of addresses, send us your problems.

USER RAM 


• Our thanks to Sebastian 
Lazareno of Ware, for telling us 
how to make the 16k Acorn User 
UserRAM work with the popular 
APTL ROM board. 

The solution is simple, just 
make (ie connect) link 6 on the 
APTL board. This switches the 
write-protect facility from slot 15 
on the APTL board (used for 
RAM) to the rest of the sockets on 
the board. Ideally a switch should 
be included in the link to allow 
you to switch the write-protect on 
and off as required. 



BLUNDERB0X 


• A line managed to get cut out 
of the April edition of First Byte, 
the line in question is: 

470 FOR pass=0 TO 3 STEP 3 

Our sincere apologies to you and 
our thanks to Gordon Sheppard 
of London for pointing it out. 

• Apologies for two bugs that 
crept into Tunemaker (March). 


Lines 710 and 1230 should read: 

710 IF notune*/. THEN PRINTT 
AB <2, 30) "NO TUNE IN MEMORY": 
i 7.= INKEY (300) : GOTO 750 
1230 IF key*="C" OR key*="c 
" THEN PR I NTT AB ( 32 , 5 ) ; SPC < 5 )

• Thanks to Jon Thackray for 
pointing out the error in the Mas- 
ter review on page 75 of the 
March issue. When specifying a 
filing system as part of a filename, 
the filing system name should be 
enclosed by hyphens, eg: 

100 LOAD --DISC-PROGRAM" 

• Sorry! Mike Rawlings’ article 
Sideways Storage in March con- 
tained a number of errors. 

In the third paragraph on page 
85 we stated listing 2 was the 
Tube compatible version - it 
should have read listing 3. And 
the caption to listing 2 on yellow 
page 114 should have read: ‘List- 
ing 2. A program for use on a 
Solidisk board’. 

On page 86, 10 lines from the 
bottom of the first column, the 
listing line numbers should have 
read 902 to 909 not 1 100 to 1170. 
Alternative lines to adapt integer 
read/write routines to handle two 
byte or three byte variables were 
missed from the yellow pages and 
you’ll find them here:

DUMPS 

This package allows full graphics screen-dumps to be 
performed down the network. 

Only one screen-dump ROM, (such as Printmaster), is 
required on the network and this is allocated as the DumPS 
station. All other stations will then be able to send graphics 
down the network to this. 

The DumPS station may also be the normal Econet Printer- 
Server, but the program will work equally well on an 
ordinary network station.,

ACORN I'SI.R MAY 1986 





We thought it was 
about time we put you 
in the picture. 


When we introduced our AMX Mouse to BBC Micro 
users, the response was phenomenal. 

And no wonder! 

It was regarded as ‘pushing the BBC to its limits’ and 
hailed by the press as ‘probably the best input device that 
has appeared recently’. The AMX Mouse brought to BBC 
Micro users the same sophisticated, positive control that 
had, until then, been the province of the more expensive 
computers, like the Macintosh. 

Now we announce a new enhanced software 
package which, can be used with a traditional keyboard or 

a stick but truly comes into its own when used with the 
IX Mouse. 

AMX Super ROM and Super Art adds colour to the 
features of the original AMX ROM, on a new 16K ROM. 

It dramatically extends the original AMX ROM facilities 
to include Pull Down Menus, over lapping colour windows, 
colour patterns and an extended Icon set in all graphic 
modes. 

Specially written to be usable with the vast majority of 
BBC Systems including 2nd processors, the Aries RAM 
Board, the BBC + Shadow mode, tape, DFS 
and ADFS. 

The kernel of the Super Art program is 
included in the 16K ROM, providing tape and disc 
users with a Mode 1 colour drawing program. 

But Super Art really comes into its own when 
used on a disc based system; a host of additional facilities 
can be selected direct from the screen. 

Colour pictures can be created in dot resolution up to 
A4 size by scrolling the screen window, over the picture. 

Other facilities include colour pattern editing - use of 
icons, additional text styles, various copy facilities and a 
superb colour Zoom. 






Pictures can be printed out in 

'colour (Integrex) or shades of black and 

grey on Epson compatible printers. 

The results can be astonishing! - you can even store 
your finished ‘masterpieces’. 

The AMX Icon Designer facility gives you further 
freedom to design and store your own custom icons for 
use in your own programs. 

This fabulous new package costs only £89.95 - a 
price as remarkable as the package itself - and includes 
a fully illustrated operating manual. 

If, however, you are afraid of mice, you can purchase 
just the software package plus the 16K Super ROM for 
just £49.95. 

You will still achieve some pretty remarkable results 
using your keyboard or joystick - not nearly as good as 
with the Mouse of course - but you can always add one 
later on for just £40. 

Then you'll really be ‘in the picture’.

When the press use such words as 
‘Phenomenal’, ‘Outstanding’, ‘Ideal’ and ‘Worth 
Every Penny', they’ve obviously discovered 
something rather special. 

But when that something turns out to be 
a product in which they are already expert, 
then it must be something very special indeed. 
The object of their enthusiasm is AMX 
Pagemaker - a revolutionary software 
program that will produce newspapers, 
posters, leaflets, notices and hand-outs - in 
fact anything where text and graphics are 
required, to an extraordinary professional 
standard. 

It’s a complete graphics design system 
and word processor rolled into one. 

AMX Pagemaker consists of two Roms 
and two discs therefore it will work on a 
standard BBC or B + micro without a Rom 
board. 



AMX Pagemaker is fully compatible with 
either the AMX Mouse - joystick or keyboard 
and requires the minimum of a single 40 track 
disc drive. It has real time graphics with fast 
continuous scrolling up and down an A4 page 
and uses Mode 0, the highest graphics 
resolution on the BBC.

control over character size and spacing: Also

EXTRA. EXTRA. 

There are outstanding facilities for

is included allowing you to load in drawings and

The cut and paste facilities include: copying, 
moving, rotating, stretching and a fantastic

AMX Pagemaker is your opportunity to 
join the publishing revolution, it comes 
complete with a comprehensive manual which 
the press describes as ‘Superb’. 

At only £49.95 the cost of the 
Pagemaker is as amazing as the program itself. 

Let’s leave the last word to the press. 

“‘Pagemaker’’ is phenomenal - it lends 
itself to creating anything where text and 
graphics are involved - notices, posters, 
leaflets, hand-outs, newsheets. Packages like 
this have been the province of the 16 - bit 
micros until now, this product is worth every 
penny of £49.95.”

virtually eliminated.

Now available the first true MEGA capacity RAMdisc for the BBC or 
MASTER computers. 

This fully compatible unit, currently available in either 1 or 2 
megabyte versions comes complete with operating software on 
ROM, power supply, battery backup and a comprehensive user 
guide, add to this our usual 12 months no quibble guarantee and 
we re sure you'll agree Morley have done it again. 

FEATURES 

1 Megabyte of RAM connected to the 1 MHz bus. 

Used with the supplied ROM software programs and files may be 
saved and loaded from the RAMdisc in the same manner as from a 
floppy disc with a large increase in speed, for example, a 20K mode 
0 screen takes about 3-4 seconds to load from disc and about 
0. 2-0.3 seconds to load from the RAMdisc. 

The RAMdisc ROM operates as a utility ROM working with the 
current filing system rather than as a separate filing system. 
Therefore ensures compatibility with any DFS. 

The RAMdisc can be selected by a * command to take the place of 
any drive number from 0 to 9. If the RAMdisc replaces a floppy 
drive as 0 for example, all commands addressed to drive 0 will be 
intercepted by the RAMdisc. The default drive no. is 4. 

Dangerous' * commands such as ‘COMPACT, ‘COPY, ‘BACKUP 
etc are intercepted and the BBC's RAM from page 2 to &7FFF is 
saved to RAMdisc workspace, and may be recovered using a * 
command. This prevents accidental corruption of any programs/data 
in RAM you may have been using at the time. The save operation 
delays the * command by just under 0.4 seconds. The BBC's RAM 
can also be saved by an interrupt-driven routine which can be 
enabled by a * command 

The filing system wedge ROM supplied supports load/save, byte 
file access, all relevant OSFSC commands, and contains a formatter, 
verifier and sector' editor for use with the RAMdisc. 

Catalogue structure allows up to 2,709 files. 

APPLICATIONS 

Programs and ROMs can be written to take advantage of directly 
accessing a single RAMdisc, allowing the possibility of spreadsheets 
with more than 512 x 512 cells, million-character documents with 
immediate access and editing of any section, manipulation of 2 
floating-point arrays each with 228 x 228 elements, a fast-access 
database with 10,000 100-character records, or even just a large 


printer buffer! 

Accessible through the user's software for direct storage of eg: 
basic procedures, variables, large arrays etc which can be 
downloaded into the BBC's RAM or read directly. (We are hoping to 
be able to supply an extended basic ROM late this year, to allow 
transparent access' to the Ramdisc, which will effectively expand 
the BBC's RAM to about 1020k.) 

OPTIONAL SIDEWAYS RAM UTILITY (suitable for use with 
any 16k SWR) 

Sideways ROM images can be saved to the RAMdisc under a 
special directory which, when enabled, will be used when an 
unrecognised * command is trapped for the ROM to load sideways 
ROMs from disc into sideways RAM. The * command will then be 
passed to the new ROM image and if still unrecognised the next 
ROM will be loaded. If no ROM loaded from the RAMdisc 
intercepts the * command it will be passed to the current filing 
system as usual. ROMs on RAMdisc can be individually disabled in 
the same manner as real' ROMs in the BBC itself. Up to 104 8k 
ROMs can be saved onto the standard 1 Mb RAMdisc, and the total 
load time (excluding time taken by the ROMs to process the 
command) for 100 ROMs is just under 9 seconds. All relevant 
control software for disabling/enabling ROMs etc. is provided. 
(Supplied on ROM.) 

EPROM PROGRAMMER now available programs 8, 16 and 32k 
EPROMS connects to the user port software available on rom or 
disc. 

Version 1 economy uncased with standard DIL socket. 

Version 2 deluxe cased with ZIF socket. 

DESFAX 7 Now you can run your own TELETEXT service! 
Incorporates the powerful editing facilities of DESIGN 7, again with 
Teletext adapter interfacing. 

Stores up to 100 of your screen designs on a 40Tk disc or 200 on 
an 80Tk. Page selection by 3-digit number HOLD, REVEAL, page 
linking, individual page delays etc. 

PLUS - a powerful CAROUSEL facility permits continuous 
slide-shows. Only one disc access for every 1 6 screens - reduces 
wear on drives. Smooth animation, variable speed text printing, built 
in printer dumps. Sample data disc and 22 page manual included. 
Beats all other systems for ease of use and versatility.

Disc Interfaces and Wb 


S olidisk offers well designed Disc Interfaces enabling 
your computer to use floppy disc drives. If you feel you 
would have any difficulty in installing it and/or 
adding disc drives, you can contact one of our 90+ Local 
Experts who will install it for you free of charge. 


The 1 770 Disc Interface 


The Solidisk 1770 Double 
Density Disc Interface has 
only four components and 
can easily be fitted even 
by a novice. The 1770 
Disc Interface is supplied 
with Solidisk 2.2 DFS 
ROM. 


The Solidisk 
1770+8271 Disc 
Interface 




If you already have a 8271 Disc Interface, then the Solidisk 
1770+8271 Interface will give you the best of both worlds. 
You can select either the 8271 or the 1770 at a flick of a 


switch. The 1770+8271 Interface is supplied with the 
Solidisk DFS+ ADFS ROM set. This is available in two 1 6K 
or one 32K ROM.

Acorn Second Processors (6502, Z80 and 32016) and Econet File Server (Level 2), and 
their capability of reading from and writing to IBM-PC DOS diskettes (with the 1770 
chip) reflect the broad range of applications supported. Both 1770 and 1770+8271 
Disc Interfaces are compatible with Acorn 1770 DNFS and ADFS ROMs.

iehesters from Solidisk 



T he Solidisk Winchesters are now available for the 
BBC Model B, B Plus and the new Master Series 
machines. They are supplied with the Solidisk 
DFS+ADFS ROM set, available in two 16K or one 32K 
ROM. 

WINCHESTER FOR SINGLE USERS 

The Solidisk ADFS can handle one or two Winchester 
drives plus one or two floppy disc drives. Files on any 
drive can be up to the drive size in length. Up to 10 
files can be open at the same time and unlimited 
numbers can be organised in a multi-level catalogue. 
Files can grow in place without risk of “Can’t extend”. 


The ADFS allows the Winchester to be “partitioned” 
into multiple user areas, accessed by CP/M (Z80), 
Panos (32016) as well as 6502 ADFS. The Acorn Z80 
Second Processor as supplied requires a new BIOS 
ROM to run CP/M.

WINCHESTERS FOR SMALL 
NETWORKS 

Solidisk will soon introduce the NET-DISC Filing 
System (NDFS). This, although using the standard 
ECONET hardware, implements a direct link between 
any workstation and the Winchester disc drive on 
station 254. No dedicated file server machine (nor any 
Second Processor to run the File Server software) is 
needed. 

The NDFS will also besuitableto network 3201 6 and Z80 
Second Processors. The cost saving is substantial, 
especially for small networks. For example, four 
workstations sharing one Winchester via such a 
network is cheaper than four stand-alone machines 
equipped with local floppy disc drives. 

WINCHESTERS FOR LEVEL 2 FILE 
SERVERS 

The Solidisk Winchester Disc Filing System (WDFS) 
ROM enables the Acorn File Server (Level 2) to use 
the Winchester in place of floppy disc drives. This will 
improve both speed and capacity. The WDFS will 
work with either the 8271 or the 1770 Disc Interfaces. 


HIGHER CAPACITY, RELIABILITY 
AND SPEED 

The Winchester drives have much higher capacity 
than floppy discs, measured in Megabytes instead of 
Kilobytes. The disc is protected from dirt by a sealed 
casing, and has a much higher inherent reliability. The 
disc rotates continuously at high speed (3600rpm) 
enabling data to be transferred 20 times as fast as 
floppy discs. 


HARDWARE REQUIREMENTS 

To use a Solidisk Winchester, you will need a 1770 
Disc Interface (Acorn or Solidisk). Master and BBC B 
Plus machines have this as standard. If your BBC B 
has no disc interface, we recommend the Solidisk 
1770 Disc Interface. If you already have the 8271 Disc 
Interface, we recommend the Solidisk 8271+1770 
Disc Interface. The Winchester drive is connected to 
the 1 MHz bus socket. 

5.25 inch WINCHESTERS 

These drives (10, 20 and 40 Megabytes formatted) are 
of established design, with low noise and power 
consumption and have the same “form factor” as a 
half-height floppy drive. 


3.5 inch WINCHESTERS 

These are of the latest technology, with even lower 
noise and power consumption in a smaller package, 
and have the same “form factor” as a 3.5 inch floppy 
drive. 

BEEB-POWERED OR MAINS-POWERED 

The Beeb-powered Winchesters are only suitable for 
use with machines fitted with the shiny, switched 
mode power supply and all Master series. The 
Winchester power lead will also support a floppy disc 
drive. In other cases, a mains-powered Winchester 
should be specified. 


THE SOLIDISK WINCHESTER RANGE 

Each Winchester drive comes with: 

— Integral power and data leads. 

— DFS (or WDFS on request) and ADFS ROM 
set. 

— One utility diskette in 5.25 inch, 80-track 
double-sided ADFS format. 

— Manuals covering the above hardware and 
software. 

— One year guarantee. 

The Solidisk Winchesters are available in the 
following packages:

SOUDISKMENOKT 

UPGRADES 


Solidisk memory upgrades for the BBC Model B offer 
excellent value for money. Their designs stand our for 
compatibility, speed, versatility and computing power 
They use the latest component technology to achieve 
the lowest possible power consumption and size at 
low cost. 


External ROM Cartridge 

This comprises an adaptor which plugs into any ROM 
socket, and a blank cartridge which will accept one or 
two ROMs. These may be of 16K, 32K or64K, 
depending on the capacity of the ROM socket holding 
the adaptor. This system is particularly useful for 
seldomly used ROMs, which are well protected by the 
cartridges. They can be installed and removed 
repeatedly without any risk to the ROMs and are 
compatible with Acorn cartridges. 


Fourmeg CPU and ROM Expansion 


The Fourmeg board plugs into the 6502 Processor F* 
socket, and two additional connections are made b\„ 
sprung clips. It also provides one 64K and three 32f 
additional ROM sockets. 


By adding faster memory and a 4MHz Processor, th 
board enables the BBC to run most programs in hal 
the time. The new Processor is equivalent to that ust 
on the Acorn TURBO board. It will run most Master^^ 


software such as the new BASIC 4 and at twice the 
speed. 

A switch selects between normal (2MHz) and fast 
(4MHz) speed. The higher speed is available to all 
ROMs and RAM installed in the Fourmeg board. Th 
rest of the machine is unaffected. 



Fourmeg Board with 32K RAM 


This comprises a Fourmeg board with 32K RAM am 
16K MANAGER ROM. This extra RAM gives Shado 
RAM and Sideways RAM capability. Shadow RAM 
supports the screen in any mode, leaving all the 
machine RAM free. Sideways RAM can contain the 
images of two Sideways ROMs or used as RAMDISt 
or printer buffer. Shadow and Sideways RAM, and tf 
four additional ROM sockets can be switched to the 
fast 4MHz speed. 


I 


32K, 64 K and 128K Sideways RAMS 


These are the most popular add-ons for the BBC 
Model B. You can start with 32K and upgrade later tc 
64K, 128K (and even 256K). The 64K and 128K RAM 
boards have two 32K additional ROM sockets. 


Solidisk Sideways RAM boards are compatible with 
most add-ons except ROM boards — which they 
replace. Sideways RAM can run almost all software 
that is normally available in ROM. Solidisk has a larg 
library of application programs. These include Word 
processor, Spelling Checker, Database, Spreadshee 
Extended Basic, Sprites, Ramdisc, Printed Buffer, 
Machine Code Monitor etc. and more than 70 
computer games especially written for Sideways 
RAM. The programs are available in three packs, eac 
of 5 discs, in 40 or 80-track formats. Pack 1 is include 
with all Sideways RAM board. Packs 2 and 3 cost 
£10.00 each (£1 .00 p&p). Pack 3 consists entirely of 
games and game design tools.

The 256K Board 

This has 256K of RAM, four ROM sockets, a 4MHz 
Processor, a 32K Manager ROM, together with 
WORDWISE PLUS — the best selling 
Word processor from Computer Concepts. 

The 256K RAM can be used as Shadow RAM, 
Sideways RAM and RAMDISK, or any 
combination of the three. 

Real Time Clock and Solidesk 

The Real Time Clock (RTC) is battery powered, 
giving accurate time and date. The “SOLIDESK” 
ROM uses the 50 bytes of battery backed RAM in 
the RTC chip to custom-configure the BBC 
computer on start-up — just like the new Master 
Machine. It also presents a friendly ICON/MOUSE 
environment — with calculator, memo and a 
number of disc operating system commands (DFS 
and ADFS). An AMX Mouse or a Marconi Tracker 
Ball is preferred as the input device, but the 
keyboard may also be used. 

Floppy Disc Drives 

Solidisk floppy disc drives are 80-track, double- 
sided, 5.25 inch, with a capacity of 640K in ADFS 
or Solidisk double density DFS. They are Beeb- 
powered, supplied cased, with power and data 
leads, and a software pack of 5 diskettes.

The Liiiciiiaster ROM 

T he Solidisk Linemaster ROM allows the BBC micro 
to communicate with other computers. In addition to 
the standard Terminal and Prestel modes, it has 
Viewdata Host Mode and the ability to autodial and 
autoanswer, all controlled by software. 

Telecom Gold 

Telecom Gold is the British Telecom electronic Mail Service 
enabling computer users to send and receive messages, 
telexes and to access many large databases. The Linemaster 
ROM allows you to use the BBC computer to communicate 
with Telecom Gold and Bulletin Boards. Its features include 
various baud rates and protocols, an elapsed time clock and 
40/80 column screen display. 

Prestel 

Prestel i the British Telecom Viewdata service. The 
Linemaster ROM offers extensive facilities to communicate 
with Prestel. If you have an autodialling Modem, a simple 
command such as ★PRESTEL 618 (for London) can put you 
"online” with the local Prestel computer. 

Viewdata Host 

In this mode, your BBC is set up as ‘Prestel look alike’. Other 
users can communicate with your computer exactly as with 
Prestel. They can browse through pages that you create 
using Linemaster. 

Modems 

The Linemaster ROM works well with all RS423 type 
modems, eg Telemod, Nightingale, Miracle etc. but not all 
modems support all the features of the Linemaster. 

Telemod 2 Modem 

The Telemod 2 is a high quality, mains powered, BABT 
approved MODEM for direct connect. This means that there 
are no rubber cups to fit the telephone into, but just a 
connection to a modern socket, with the telephone plugging 
into the back of the modem. The modem supports 1200/75 
baud (V23) communications protocol as in Prestel and 
Telecom Gold.

MULTIFORM Z80 

The MULTIFORM Z80 2nd Processor for the BBC Micro — 
opens the horizons of CP/M software to the BBC micro user 


I * Will enable running of almost any CP/M applications 
software 

* Will enable transfer of data between different disc 
formats 

* Emulates the two terminals most frequently used by 
CP/M software 

MULTIFORM Z80 interfaces directly to a normal BBC 
micro requiring no hardware changes. It is supplied with 
OS/M operating system in rom which can run all software 
that obeys CP/M 2.2 constraints and its configuration is not 
hardware specific. 

MULTIFORM Z80 is truly flexible and can be used with any 
BBC micro drive system, single or dual drive, 40 or 80 track 
format and single or double sided. Unlike other currently 
available Z80 processors for the BBC micro, there are 
absolutely no restrictions on the type of drive that can be 
used with the MULTIFORM Z80. 

MULTIFORM Z80 plugs into the 1MHz bus connector of 
the BBC micro. It is mains powered and does not put any 
extra load on the BBC’s psu. The data cable can be several 
feet in length, allowing convenient siting of the 
MULTIFORM Z80, unlike present second processors, which 
have 8" cables. 

The formats supplied include: Acorn Z80, RML 380Z and 
480Z, Torch (read only), Osborne, Televideo ... we also 
offer to configure other formats at an extra charge.” 

Rom based OS/M operating system is fully compatible with 
Acorn’s single and double density disc interfaces. Installing 
the OS in rom allows more space on discs for programs and 
data and response to system commands is very fast. (Note: 
Single density DFS will only read/write to single density 
CP/M formats). 

MULTIFORM Z80 can format, read or write from a very 
wide range, of CP/M disc formats. On a dual drive system, 
the drives can be set up independently to run two different 
formats at the same time. This will enable: 

* The user to buy software from a very wide range of 
j suppliers without having to worry about the type of 
[ format supplied. 


* Interchange of valuable data and files among users of 
various CP/M computers. 

* Using a system at home for preparing data required in the 
office. 

* Software writers/developers to write software in any one 
format and transfer it to any other format without having 
to pay for expensive porting charges. 

MULTIFORM Z80 is supplied with a library of a number of 
popular CP/M formats and a utility disc containing a 
program for creating files for the additional formats. Each 
library can load 32 formats and there are no restrictions on 
the number of libraries that can be created. 

The utility disc also contains a program to interconvert 
ASCII texts wordprocessed on a normal BBC and under 
OS/M or CP/M. 

MULTIFORM Z80’s terminal emulation includes the 
ADM-3A, the HAZELTINE 1500 and the BBC VDU 
making the installation of most of the well known CP/M 
software easy. 

MULTIFORM Z80 converts your BBC computer into an j 
almost universal CP/M machine and adds the power of 
being able to run two different formats simultaneously, 
which currently is possile on only the very sophisticated 
specialist machines. 

For any one working or intending to work in a CP/M 
environment, MULTIFORM Z80isan indispensable tool. 

In offices where there are a multitude of CP/M machines 
and a few BBCs, MULTIFORM Z80 will prove to be 
invaluable for transferring data between the various CP/M 
machines. 

MULTIFORM Z80 (including utility disc, library disc and 
manual) £299 + £4 p&p 

(When ordering please specify ihe type of DFS, 
MULTIFORM Z80 will be used with)

NOVACAD 

Computer Aided Draughting 
for the BBC Micro 


A sophisticated CAD package with unique facilities which 
until now were confined to custom built CAD packages. 

Whether you want to draw a complex electronic circuit 
diagram or plan your new kitchen or simply draw a cube 
NOVACAD will help you do it better and more easily . 

All you need is a BBC micro model B fitted with Acorn DFs 
and a single disc drive. If you have a 6502 2nd processor and 
a dual disc drive NOVACAIVs capabilities are further 
enhanced. 



Very user friendly with all commands and controls from 
the keyboard. Special windowing techniques make 
available to the user almost one million dots allowing a 
|ot more detail to be put on the drawing than one would 
normally expect the BBC to be capable of. The drawing 
can be 4 windows across and 5 up. 

Libraries of user defined ICONS such as electronic 
symbols can be created easily and edited even in the 
middle of drawing another diagram. ICON size is not 
limited to a number of pixels. An ICON can contain up 
to 500 lines, so complete drawings or sections of large 
drawings can be saved as ICONS for use with other 
drawings. 

ICONS can be called by name from a library into any 
part of the diagram and can be moved, enlarged, 
reduced, rotated in 90° steps and have mirror images 
made before being finally positioned. 

Shapes can be copied on the screen as many times as 
required. 

The zoom facility allows the user to magnify any section 
of a drawing by up to 20 times to make it easier to insert 
details. 


* Any two colour can be used in mode 4. 

* Up to ‘8 levels’ can be used to produce multi layer 
drawings, and then user can decide which levels are to 
be displayed. This can be particularly used in pcb 
drawings, architectural drawings with details of the 
services behind the walls displayed only when required 
and many other such applications. 

* Text can be added at any position vertically or 
horizontally. 

* Use of 2nd processor will allow use of any 4 colours, 
higher pixel density drawings and considerably faster 
operation. (NOVACAD without the 2nd processor is 
faster than any other CAD package we have seen for the 
BBC). 

* Powerful delete facilities allow deletion of single lines or 
whole sections with minimum of key presses. 

* Printer dump for Epson compatible printers 
incorporated in the software which allows a full or a 
sectional screen dump. 

* An optional plotter utility contains a plotter 
configuration program allowing the user to configure a 
program for his plotter. Pre-configured programs are 
included for a number of popular plotters. 



Horizontal and vertical displacements can be measured 
in any user defined scale. 


NOVACAD will prove !o be an invaluable teaching aid in 
technical schools and colleges and for anyone involved in 
draughting it will be an ideal labour saving tool.

comprehensive manual £79 (c)

HINTS & TIPS 

Martin Phillips offers a few tricks to help with debugging and a way to split long programs up into 
smaller, more manageable, pieces to try to overcome the Beeb and Electron’s lack of memory 



SQUASHING 


THE BUGS 

I have come to realise that most programs do 
not work first time; indeed most programs 
don't work the second or third times either! 
Just sitting and staring at the program or the 
listing usually offers very little hope of solving 
the problem. 

If it’s a program you’ve written yourself, it 
is often the silly things that cause the most 
trouble; if it’s a magazine listing then it is 
usually a typing mistake such as ‘O’ instead of a 
‘O’, or missing out a line or part of a line. 

The usual way of solving the problem is trial 
and error - keep changing bits and pieces until 
something happens, or keep comparing the 
typed-in program with the printed listing, 
hoping to spot the difference. This often 
works, but there’s far more satisfaction to be 
had by being able to predict the part of the 
program where the fault is likely to be, and 
trying to spot it. 

One usually gets a better understanding of 
programming on the way, and it’s a process 
which gets easier with time. I get comments 
from readers who say that they hate having to 
debug programs, yet those same people will 
spend hours playing adventure games. 

Debugging programs can be just as much 
fun, and very satisfying - equally it can be just 
as annoying and frustrating! There are, 
though, a few tricks to make the debugging 
process much easier. 

• Always save copies of the program regu- 
larly, so that if something happens to the 
version you’re working on, you can load in the 
previous one and only a part of the work will 
have been lost. 

I always save programs with filenames that 
give a version number, eg, SAVE“PROG05”. 
This is also useful when you get into a mess 
with the changes made, as you can retrace your 
steps back as far as necessary. If you’ve a 
printer and an unlimited supply of paper 
(printers are rather effective machines for 
wasting paper), it’s not a bad idea to save a 
print out when saving to disc, and mark each 
print out with the version number. 

• You should always put the ON ERROR 
statements in as REM statements until the 
program works. That way you can get some 
idea of what is going wrong. Once the pro- 


gram runs, the REM can be removed and the 
ON ERROR restored. 

• Similarly, always REM any *FX200 call 
which disables the Escape key and alters the 
function of the Break key. 

• If it’s not obvious where a program is 
going wrong, use the STOP command. 

Insert the word STOP at a point where you 
are fairly certain the program will run to, and 
then run the program, moving the position of 
the STOP through the program line by line (or 
a few lines at a time) until you come across the 
offending line. I usually put STOP at an in- 
between line number so that it’s easy to delete 
and move on. 

When a program stops because of an error, 
it’s easy to miss the actual error or the error 
line. All is not lost, though. Simply type 
REPORT to see the error message again, and 
type PRINT ERL to find the line number. If 
the result is ‘at line 0’ with no error given, then 
the program has well and truly crashed. An 
example of when this can happen is with Basic 
1 and the INSTR function: when the search 
string is longer than the string being searched, 
the program crashes and this cryptic error 
message is given. 

• If you know an error exists in a certain 
piece of code, and the problem is a stubborn 
one, then define a function key to list that part 
of the code on the screen. For example if the 
fault in the code lies between lines 180 and 270 
then program function key 0 as follows: 

*KEY0 MODE7 ! M ! N LIST 180, 270 ! M 
(Or MODE6 for the Electron.) 

This idea is especially useful when the function 
of the editing keys has been changed by *FX4 
or the auto-repeat has been switched off. 
Another key (or the same one) can have the 
extra code: 

*KEY1 *FX4,0 ! M *FX12,0 ! M 
*FX4,0 sets the editing and cursor keys back to 
their normal editing functions, and *FX12,0 
puts the key auto-repeat and delay back to its 
normal setting. 

Using the function keys in this way can save 
a lot of typing (and therefore possible mis- 
takes) and makes debugging much easier. 

• A common error is ‘No such variable’. 
Instead of having a vague look at the offending 
line of code, try to run the program. List the 
line and print out all the variables to find which 
one does not exist. This is very easy to do. An 
example program line of: 


230 FOR J = start TO end STEP N 
has three variables which need to be pre- 
defined: ‘start’, ‘end’ and ‘N’. Therefore type: 

PRINT start 

PRINT end 
PRINT N 

and with luck the problem will now show 
itself. It’s then a task of checking back through 
the program to find where that variable should 
have been defined. A common fault is a 
spelling mistake in the variable name, or 
capital letters where lower case should have 
been used. Sometimes all the variables give a 
value and you’re almost back to square one, 
but now the fault is easier to spot - obviously 
one of the variables is not what it seems on the 
screen. Look at the following line. 

230 FOR J = start TO endSTEP N 
Here a space has been missed out, and the 
dreaded ‘No such variable’ message appears 
because the computer thinks that ‘endSTEP’ is 
a variable. 

This technique is valuable with arrays, 
where things such as subscript errors can be 
very tricky to spot, and being able to print out 
what’s stored in a particular array can be 
enlightening. A peculiar quirk of BBC Basic is 
that an element of an array can be printed in the 
same way as a normal variable after the 
program has run, but only if the program has 
not been edited. 

As soon as a line of text is altered, the 
pointers for the array are lost and the elements 
cannot be printed out. 

• If you have tracked a difficult problem 
down to a procedure in the middle of the 
program, and it takes ages to run the program 
to that point, then save the program, delete 
everything but the procedure and write a short 
dummy program call it up with the correct 
variables. I find this a useful technique when 
writing programs as I can test a possibly 
problematic procedure before putting it into 
the program. Several examples of this tech- 
nique have appeared in Hints & Tips, where I 
present a listing with a short sample program 
to show how it runs - listing 1 and 2 on the 
yellow pages are good examples. 

• When editing listings that have no space 
between the line number and the actual listing, 
it’s a good idea to use L1STO 1. 

• The error message routines in BBC Basic 
are not too bright, and they are easily fooled. 
Either the error message itself can be incorrect, 


ACORN USfcR MAY 1986 


51 



HINTS & TIPS 


or the line number given can be different from 
the line where the error actually is. 

PRINTTAB(3,4) “HELLO” 
will print “HELLO” near the top of the 
screen, but if the TAB statement is missed out: 
PRINT (3,4) “HELLO” 
the error message ‘Missing)’ is given - obvi- 
ously incorrect as it’s the statement TAB that’s 
missing. When this error occurs, count the 
number of right and left brackets in the line - 
they must be equal. 

It is possible to have an error line different 
from where the error occurred; ie, the OSCLI 
routine needed by Basic 1 users: 

10 DIM A 50 
20 X%= A MOD 256 
30 Y%= ADIV256 
40 $A= “HELP” 

50 CALL &FFF7 

When run this lists all the ROMs in the 
machine - it’s the same as typing *HELP, 
except it’s been called from within a program. 
If a mistake is made in line 40 thus: 

40 $A= “HELPP” 

then an error message is given, not at line 40, 
but at line 50. In this example it is easy to find 
the problem, but when the OSCLI routine is a 
procedure called from several points in the 
program, finding the error can take some time. 
A common example occurs with the READ 
and DATA statements. The following pro- 
gram reads five numbers, stores them in an 
array and also prints them on the screen. 

10 DIM A(5) 

20 FOR N% = 1 TO 5 
30 READ A(N%) 

40 PRINT A(N%) 

50 NEXT 
60: 

70 DAT A 1,2, 3, 4, 5 

However, if a mistake is made in the DATA 
statement, for example: 

70 DATA ,1,2, 3, 4,5 
the error message says: 

No such variable at line 30 
• Errors are often very difficult to spot when 
they are in long multi-statement lines. The 
solution here is to split these lines up so each 
statement is on a different line, for example: 

10 DIM A(5):FOR N% = 1 TO 5:READ 
A(N%):NEXT 
20 . . . 

can be split up to become: 

10 DIM A(5) 

11 FOR N% = 1 TO 5 

12 READ A(N%) 

13 NEXT 
20 . . . 

This is where it helps to have program lines 
numbered in tens. 



PROGRAMS 


IN PIEC ES 

A limitation of the BBC micro and Electron is 
the lack of memory when using graphics. In 
modes 0, 1 and 2 there is less than 5k when 
using discs. This has been overcome to some 
extent with the Master and BBC B4- with 
shadow modes, but can still cause many diffi- 
culties. However, careful program design can 
often overcome this limitation, and even have 
several advantages. For instance, imagine writ- 
ing a program on a 512k machine and having 
perhaps 100k of program to type in from a 
listing and then debug! 

By now most readers will be familiar with 
the idea of procedures, and how they are able 
to break a program up into manageable chunks 
so that each can perform a specific function. 
This makes understanding the program much 
easier, and enables problem areas to be pin- 
pointed quickly and errors cured. 

There is a technique whereby some proce- 
dures can be stored on disc and pulled into the 
program as and when required, but this needs 
very careful planning, and can be quite difficult 
to debug. 

A simpler approach is to divide a long 
program which uses graphics into several 
shorter programs, if possible, so it’s even easier 
to follow and sort out any difficulties. A simple 
example is in the use of instructions, which can 
be given in a separate program which loads in 
first. There are other not so obvious advan-

Listing 1. Defines five strings and stores them . . . 


tages to this approach: for instance, BBC Basic 
does not do much ‘garbage’ collection so that 
in a long program a lot of memory can be taken 
up with spaces reserved for variables, strings 
and arrays that are no longer required but 
which the computer does not clear out. Then if 
memory is tight, after the program has run for 
a bit it crashes with the dreaded ‘No room’ 
error message. However, if the program is 
broken up, with new programs being 


Htre are the strings: 

This is the first line of text 
This is the second line of text 
This is the third line of text 
This is the fourth line of text 
This is the fifth line of text 


Here are the variables:

The strings stored by listing 1 are printed out by the chained listing 2 


52 


ACORN USCR MAY 1986 




CHAINed in as required, all this space is 
cleared out when the new program is 
CHAINed. Also, as there will be fewer vari- 
ables, strings and arrays in a short program, 
there will be less of a problem with garbage 
collection anyway. 

Splitting up programs into smaller pro- 
grams can create problems, though. The main 
one is, how does one transfer data from one 
program to the next? If there are just a few 
variables, this is easy. The resident integer 
variables A% to Z% are not cleared when a 
new program is loaded, so 26 integer variables 
can easily be passed to subsequent programs. 
How can one pass strings and even arrays? 
Here is a technique which is very simple to 
operate and can be made to work in a wide 
variety of situations. All it does is to store 
integer variables, strings or arrays in ‘safe’ 
memory areas, so the next program can use the 
reverse process to ‘load’ them in again. 

Listing 1 (opposite) is the program to define 
five strings and store them, together with five 
integer numbers, into memory locations start- 
ing at &3000. Listing 2 then retrieves the 
strings and numbers and prints them out. 
When trying this out, do remember to save 
each program first. 

A string can be placed into memory by using 
the $ indirection operator, so $C% will place a 
string into memory starting at the memory 
location given by C%. It will also place a 
return character (&0D) after the string to 
indicate its end, which needs to be taken into 
account when incrementing C%. !C% will 
store an integer variable into four memory 
bytes starting at the location given by C%. 

Listing 2 must be saved as H 4* T2 for the 
first program to be able to CHAIN it in. When 
it has loaded and displayed the variables and 
strings, try pressing CTRL-Break and then 
type OLD followed by RUN. The data should 
still be there, making it a very useful technique. 

Perhaps the hardest thing is to find a ‘safe’ 
area of memory. This can be any part of 
memory which will not be overwritten by the 
program, or by the screen memory area, or by 
any memory area used by the computer itself. 
It is often advisable to avoid the first two bytes 
of a new page of memory if it is below PAGE, 
as the operating system often puts markers at 
the start of a page, eg, PAGE&900 (locations 
&900 to &9FF) are the RS423, sound and 
speech workspace. Often these are not used, so 
that this memory area can be used. The 
operating system puts a marker (in this case 
&10) at location &900, so to avoid any 
problems, it is best to start storing at location 
&902. Thus when Break is pressed, the first 
byte or two of data will not be corrupted.

FOR 


MASTERS 

For those who’ve bought a BBC Master, and 
put a function keystrip into the new holder 
only to find that you cannot get it out again, 
try sticking a write-protect sticker on the 
keystrip to make a small tab - it can then be 
removed easily. 


While on the subject of write-protect stickers, 
here is a tip for those who are also interested in 
car maintenance. If you have a timing light but 
it is not bright enough to show the markings 
on the flywheel, cut a notch in a silver write- 
protect sticker and stick that in the right place 
on the flywheel. This then reflects the light so 
that the timing can be set, the notch indicating 
the correct timing point. 


When making a backup of a disc, always make 
sure that the disc to be copied has a write- 
protect sticker on it. 


Vertical print is simple with the use of text 
windows. This program gives an example: 
10CLS 

20 VDU28,20, 16,20,5 
30 PRINT “Acorn User” 

40 VDU26 

Notice that the left-hand and right-hand co- 
ordinate of the windows are the same value. 
Try leaving off the VDU26 (restore default 
window) to see why line 40 is necessary. 



QUICKFIRE 

QUESTIONS 


Darren White from Chelmsford would like to 
know how to disable any ROMs in his ma- 
chine. First find out the ROM number (see 
Hints & Tips February ’86) and then add this 
to the number &2A1. So, if the ROM in socket 
three is to be disabled, type ?&2A4 = 0. When 
this has been done, pressing Break will reset it, 
so if a disc auto-boot program is to be loaded, 
type either: *EXEC 1BOOT or *Rl’N 
1BOOT. Depending on the type of 1BOOT 
file, this is exactly the same as using Shift- 
Break, except that the computer is not reset 
first. If it’s possible to catalogue the disc, at the 
top right it will tell you whether to * FIX EC 
(option 3) or *RUN (option 2) the disc. 

Mr Gri mason from Portadown would like to 
know if his Wordmse Plus is faulty because it 
will not display more than two or three pages 
in the 80 column preview mode. This is quite 
normal: Wordwise Plus reverts to 40 column 
preview mode if there is not enough memory 
space left to go into 80 column mode. 

Mrs Chesterfield from Bristol wants to know 
how to calculate how many data files can be 
stored in memory and on disc. 

First the number of bytes in each record 
needs to be calculated. 

To do this add one to the number of bytes 
allocated to each field in the record and then 
add these lengths together. 

To find out how much memory is available 
in the computer to store a complete record, 
you will first need to run your database 
program so that it sets all its own workspace. 
Then leave from the program by pressing the 
Escape key and enter: 

DIM P% - 1 
PRINT HIMEM-P% 

The figure printed will be the amount of ‘free’ 
memory remaining. All you need do is divide 
the number of bytes required for each full 
record into this to give you the total number of 
records. 

On disc the maximum storage space (assum- 
ing a newly formatted blank disc) is: 

(number of sectors-2)*256 
On a 40 track disc this gives 97,280 bytes and 
on an 80 track disc 199,680 bytes. Again, 
dividing the record length into this will give 
the maximum number of records. 

If you need to have other programs co- 
resident on the disc you’ll have to subtract the 
file length of each from the bytes free value 
before dividing this by the record length.

TRANSFERRING 
YOUR AFFECTIONS 

First Byte offers advice on the best way to transfer 
your programs from tape to disc 


In the early days with my computer, my big 
ambition was to get the cash together to buy a 
disc drive. This was about four or five years 
ago and my first disc drive was a single sided 
40 track affair, which (I think) cost about £300! 
Nowadays such drives can be picked up at a 
fraction of the cost - less than £50 in most 
cases, while an 80 track drive can be yours for 
around only £80 (or about £150 for a Plus 3 
for the Electron). 

I don’t propose to spend this month’s First 
Byte chatting about disc drives but about the 
problem that confronts all users (other than 
lucky Master owners!) who upgrade from tape 
to disc - the subject of transferring your 
programs and games. If you are looking for 
information on disc drives 1 would direct you 
to two articles by Bruce Smith in the July 1985 
and February 1986 issues of Acorn User. 

When confronted with a problem of this 
type it’s a good idea to break it down first into 
the steps you need to achieve, and then develop 
these into a program. The steps required for 
the tape to disc program are: 1) select tape 
filing system; 2) load program; 3) select disc 
filing system; and 4) save program to disc. 

Overwriting software 

The first problem you come across is that if 
you write a program to do the above, loading a 
subsequent program from tape will overwrite 
your transfer software! You can get around 
this, though, by using a function key to hold 
the instructions. For example, if we have a tape 
file called GRAPHICS, the program steps that 
would be required are: 

♦TAPE 

LOAD “GRAPHICS” 

♦DISC 

SAVE “GRAPHIC” 

We’ve had to shorten GRAPHICS to 
GRAPHIC because disc filing systems will 
allow only seven characters in a filename. The 
key definition therefore becomes: 

♦KEY0 *TAPE | MLOAD“GRAPHICS” ! 
M*DISC ! MSAVE “GRAPHIC” j M 


Pressing function key fO at any time will 
therefore effect the transfer. 

The above method works happily with 
straightforward Basic programs, but it won’t 
work with machine code programs or data files 
or text files from a wordprocessor, for exam- 
ple. These can be transferred but you have to 
use the operating system equivalents of LOAD 
and SAVE; that is, *LOAD and *SAVE. Both 
of these star commands need information other 
than just the filename - they need to know the 
start and end addresses of the file in memory. 
To find this out, first catalogue the program 
with the tape system’s extended catalogue 
information facility enabled. To do this type 
♦OPT 1,2 after which the file can be cata- 
logued. If our example file GRAPHICS was a 
data or machine code file on tape, the proce- 
dure would be: 

♦OPT 1,2 
♦CAT GRAPHICS 

When the last block in the program has been 
reached the extended information will be dis- 
played - it might look like this: 

GRAPHICS 01 0200 00002000 00002000 
The information presented here, in order, is: 
GRAPHICS the filename 
01 — the block number 

0200 — the file length 

00002000 — the *LOAD address 

00002000 — the execution address 

The filename is obvious. The block number 
tells you the number of blocks used to save the 
program, a block being 256 bytes long (if you 
listen to a computer tape it’s the noisy bit!). 

Hex values 

The file length is a hexadecimal value and 
leading zeros can be ignored, so the length of 
this file is &200 bytes. This value, combined 
with the file load address (&2000) is what is 
needed to transfer a simple data or text file 
from tape to disc. 

To transfer this file we need to first *LOAD 
the file ignoring leading zeros to the specified 
load address - &2000 in this case - and then 


♦SAVE the file by specifying the start address 
(as given above) and the end address. To 
calculate the end address we simply add the file 
length to the start address: 

&2000 + &200 = &2200 
The format of the *LOAD and ♦SAVE com- 
mands is: 

♦LOAD “Name” LLLL 
♦SAVE “Name” LLLL EEEE 
where LLLL is the hexadecimal load address 
and SSSS the end address, also in hex. 

Using the format described above, the trans- 
fer sequence becomes: 

♦TAPE 

♦LOAD “GRAPHICS” 2000 
♦DISC 

♦SAVE “GRAPHIC” 2000 2200 
As before, this can be put into a function key if 
so desired. 

Machine code programs can be loaded in 
from tape in exactly the same way, but before 
they can be saved we have to know their run or 
execution address, which is the last value 
specified in the extended information. In the 
above instance it was &2000, the same as the 
load address, but this may not always be the 
case. The specification for a *SAVE of a 
machine code program is: 

♦SAVE “Name” LLLL EEEE RRRR 
where RRRR is the run address. If GRAPH- 
ICS was a machine code program the ‘save’ line 
would need to be amended to: 

♦SAVE GRAPHIC 2000 2200 2000 
The above ‘star’ method is fine, as long as the 
load address for the program is not less than 
&1900 (&1D00 for the Advanced Disc Filing 
System [ADFS]). If it is lower, problems can 
occur when trying to transfer it because the 
value of PAGE is at least &1900 when a disc 
filing system (DFS) or ADFS is installed. On a 
tape-based system PAGE is set to &E00. The 
DFS therefore claims at least 2.75k of memory 
in which it can perform its functions. Loading 
a program into this area of disc workspace can 
result in the corruption of the program before 
you save it. In the case of ADFS you will 


54 


ACORN USHR MAY 1986 





probably not even be able to save the program 
in any form at all as it will corrupt the disc 
catalogue which the ADFS stores in this area 
of memory. 

Saving the data 

In cases such as these you can load the data or 
machine code into a ‘foreign’ area of memory 
and then save it as though it was saved from its 
expected address. 

As an example, suppose a tape-based pro- 
gram called DUMP gave the following extend- 
ed catalogue message: 

DUMP 03 0300 OOOOOF05 
Here we have a file &300 bytes long, with a 
load address of &F00 and an execution address 
of &F05. 

To load this file at a new address, proceed as 
usual but use a new load address (&2000 for 
example) thus: 

*TAPE 

♦LOAD DUMP 2000 

The ♦SAVE command can have a fourth and 
final parameter added to it - the relocation 
address - and it’s this which is used to fool the 
DFS into adding the correct loading address to 
it. The format of the command in full is: 
♦SAVE “Name” SSSS EEEE RRRR 
AAAA 

where AAAA is the actual load address. To 
complete the transfer the following two lines 
are required: 

♦DISC 

♦SAVE “DUMP” 2000 2300 0F05 0F00 
The above raises the question of how we get 
the program to load and run below the DFS 
value of PAG FI: more on this in a moment. 

The approach detailed so far for loading and 
saving programs, data and machine code files 
is effective, but if there are a large number of 
files to be transferred, tedious. Listing 1 on the 
yellow pages is an automatic program which 
will do the lot for you - all you need do is run 
the program, making sure that the tape con- 
taining the programs to be transferred is in the 
cassette recorder and a blank formatted disc is 
in drive 0. The program is intelligent and 
copies all types of files. 

Once you have your programs on disc you 
can, in most instances, simply load them in and 
use them as normal. There are times though, 
when perhaps because of the program’s size, it 
will only run as though it is a tape-based 
program with PAGE set to &E00. 

Such programs can still be used but you 
need to employ a routine to relocate the 
program. In simple terms you need to load the 
program in from disc; select the tape filing 
system; move the program down to &E00; 
and then run it. 

Basically what’s required is a short routine 


FIRST BYTE 


which takes the bytes of memory from PAGE 
to TOP (the top of your program) and puts (or 
pokes) them into memory starting at &E00, 
and ends by resetting PAGE to &E00 and 
running the program. Listing 2 on the yellow 
pages can be added to the end of your program 
to perform the task. 

After you’ve loaded your program in from 
disc, type: 

GOTO 10000 

and the program will be relocated and run. 

Machine code programs can be treated in 
exactly the same way, but PAGE and TOP 
should be replaced by the load and end address 
of the file, and the RUN by a CALL to the 
execution address, ie, CALL &F05 in the case 
of the DUMP program described earlier. 

Protected files 

All that I’ve described so far will work happily 
provided the software you are tyring to trans- 
fer is not protected in any way. Protection is, in 
many cases, ingenious programming by the 
software writer that will not allow you to make 
extra copies of the program. If you can’t 
catalogue the program or get it to produce 
extended messages, the program is almost 
certainly protected. 

Programs of this type can still be transferred 
but need transfer routines which are too 
sophisticated to be described here or, due to 
their length, listed in Acorn User. However, 
there are many ROMs available that will 
transfer programs from tape to disc for you. 

Watford Electronics, for example, sell 
Transferor. This will cope with most (though 
not all) protected programs including very 
long adventure programs. It is menu driven 
which means that it provides you with options 
which you select by pressing a particular key. 
Transferor is for the BBC' micro. 

Slogger Software markets T2P3 (a Tape to 
Plus 3 transfer ROM) for the Electron which is 
easy to use, though you’ll need a ROM 
expansion box into which to insert the ROM. 

Replay is the current state-of-the-art answer 
to tape to disc transfer, available for the BBC] 
B. This consists of a ROM and some hardware 
which must be attached inside the computer. 
Once installed it will cope with virtually any 
program you care to put to the test. 

To sum up, transferring your own programs 
from tape to disc is straightforward and listing 
1 will cope well. Commercial software is 
generally protected to prevent copying and in 
such instances you’ll need a ROM to perform 
the task for you. 

How to enter and use the program 

The T2D (Tape 2 Disc) program is written 
entirely in Basic and should present you with 


no real problems' when entering it. When it is 
complete you should save it to disc using the 
filename ‘T2D’. 

To test the program take a blank tape and 
save about half a dozen programs onto it, one 
after the other (you could use the T2D pro- 
gram and save it six times using a different 
filename each time). When you have done this 
put a blank formatted disc into drive 0 in fact 
you can use a disc containing files as long as 
there is enough room to take the files from the 
tape. Load and run the T2D program, and 
follow the instructions presented on the 
screen. After you press any key the first 
program will load from tape. The tape will 
then stop and the program will be saved to 
disc. This process will repeat until all files on 
the tape have been loaded in and saved to disc. 

The program cannot tell when all the files 
have been transferred. Once you are sure that 
they have been, or the tape has wound through 
to its end, press the F]scape key. Type *DISC 
followed by *CAT. You should see the six files 
in place and these can now be loaded in and 
used in the normal way. 

The program relies on the cassette recorder 
having a motor control on it so it can be turned 
on and off while programs are being trans- 
ferred. If your cassette player does not have 
this facility, you’ll need to do one of two 
things. First, to stop the tape after each 
program has been loaded in, or second, to 
leave a few seconds gap on the tape between 
each file as you save it. In practice, however, 
you will probably not need to do either as the 
transfer will be so quick the tape will not have 
reached the next program when T2D comes to 
load it in. 

If you have a double sided or dual drives you 
can adapt the program to save on to whichever 
disc surface you want, simply by adding an 
extra line: 

315 *DRIVE2 

Insert the drive number to suit yourself. The 
above would save the file on drive 2.

MASTERING THE 


ELECTRON 

Sir, Congratulations to Acorn on 
the latest computer, the BBC Mas- 
ter - it’s now by far the best on the 
market. I especially like the ROM 
facilities, pinched from the Elec- 
tron’s Plus 1 unit. 

I’m an Electron owner and al- 
though I like the Master very 
much I will probably stick with 
my machine for a while. 

Which brings me to the point of 
this letter. It is my experience 
(humble though it may be) that 
tape and disc drives are a pain in 
the backside and that permanent 
memory RAM units are the solu- 
tion to the problem. 

If the boys at Acorn could 
upgrade the Electron’s Plus 3 
unit, replacing the discs with a 
solid state permanent memory fil- 
ing system and include with it a 
numeric key pad, it would please 
me no end.

LEGAL AND 
DECENT? 

Sir, I have recently come across a 
situation that is probably very 
familiar to those readers of Acorn 
User who have tried to obtain 
equipment from mail order com- 
panies, but I have seen little com- 
ment on this subject in the corre- 
spondence columns of any of the 
popular home computer maga- 
zines. I refer to the highly mislead- 
ing advertisements that regularly 
appear from many large and fam- 
ous companies offering equip- 
ment that they do not carry in 
stock, have not had in stock for 
some time, and whose true prices 
bear little or no relation to the 
figures quoted in the published 
advertisements. 

A recent attempt to buy disc 
drives gave plenty of examples of 


Letters 

Write to Letters, Acorn User, 141-143 Drury Lane, London WC2B 5TF 


this dubious practice. A well- 
known company received my or- 
der, but I heard nothing for two 
months, in spite of writing again. 
Eventually, I phoned them, only 
to hear they had not had the item 
in stock for the whole period in 
question and wouldn’t be getting 
them for another month. Mean- 
while adverts, with steadily rising 
but entirely fictitious prices, regu- 
larly appeared in the press. The 
likely price applicable when they 
would have stock to send out 
would be some £50 more than 
that published when I had origi- 
nally ordered. 

I then telephoned every compa- 
ny in the February issue of Acorn 
User claiming to sell this particular 
item. Most did not have the disc 
drive, and those which did were 
selling at prices substantially 
above those advertised. 

This occurred so consistently 
that it was hard not to believe that 
the microcomputer business has 
adopted the practice of placing ads 
of goods they know they cannot 
provide, at prices they have no 
intention of honouring. 

Another example was Gemini’s 
Datagem, offered by two compa- 
nies at big discounts. One compa- 
ny has advertised this price regu- 
larly, in spite of having no stocks 
of the item. The other ‘sold out’ of 
the reduced price stock while the 
ad was still current. 

I think we can all accept price 
rises, selling out of stock and 
similar events. However, the habit 
of advertising ‘fantasy’ goods at 
‘fantasy’ prices seems more a cyni- 
cal manipulation of the customer. 
Presumably the companies bene- 
fit, though I rapidly saw the ad- 
vantages of going to a High Street 


dealer. Docs the home computer 
trade really need to work like this?

There have been a spate of 
complaints about disc drives, 
and the Advertising Standards 
Authority investigated Akhter, 
Microman, Tiger, Twillstar, 
Viglen and Watford. In each 
case the company was judged 
to have been caught by an un- 
expected price rise and, be- 
cause it had acted in good faith, 
the complaints were not 
persued. Vigilance is vital and 
the motto is to check before 
ordering. 



ART INTO 


SUPER ARL 

Sir, May I point out a small 
inaccuracy in Jonathan Inglis’ re- 
view of the AMX Super Art pack- 
age in the March edition of Acorn 
User. He expressed disappoint- 
ment in being unable to load 
pictures previously created with 
the old Art programs. 

It is perfectly possible to load 
old screens into Super Art - you 
simply have to select option 
LOAD B&W (black and white) 
from the Goodies menu and then 
supply a filename. 

The picture can then be saved 
in Super Art format by selecting 
option CREATE from the file 
menu. The picture in figure 1, for 
example, is one of several that I 
have successfully transferred. 

Keep up the good work (Acorn 
User and A MSI).

FLIGHT 


KNOWLEDGE 

Sir, I am extremely interested in 
flight simulation programs. I have 
all the programs available that 1 
have knowledge of, but I’m sure 
there are more. 

I am looking for someone to 
help in designing a definitive 
flight simulation program. 

1 Through my knowledge of real 
flying, general interest in aviation 
and seeing the good and bad parts 
of the many flight programs that 
are around at the moment, I feel 
that I am in the position to be able 
to offer the basis for a very realis- 
tic package indeed. 

I have no knowledge of pro- 
gramming the BBC B but of 
course I have basic knowledge of 
the machine’s operation. 

I would be very pleased tc ^ear 
from any individuals, companies 
or software houses who have a 
flight simulation program which 
is not generally available or from 
any party interested in my idea. 1 
really would like to get this ‘off 
the ground*!

LETTERS 



This lady was produced by Graham Owen - can you help him create better? 



128k B + 


SHADOW 

Sir, When February’s issue of 
Acorn User arrived I was very 
interested to read Joe Telford’s 
article on shadow RAM, having 
bought a 128k BBC B+ with 
View i three weeks earlier. 

On the other hand I was some- 
what amazed to see the news 
about the new Master series of 
machines. I think Acorn has a 
cheek to run two page adverts for 
the 128k B+ one month and then 
announce its successor the next! 

I am very pleased with my new 
machine but would have hung on 
and saved myself the cost of View 
if I had known about the Master - 
or for only a tenner or so more 1 
could have had an on-board sec- 
ond processor. 

Anyway, could you please ask 
Mr Telford if he would write 
about uses for the 12k of sideways 
RAM above the screen RAM on 
the B + - is there any way to use it 
as a printer buffer, for instance? 

Meanwhile, 1 console myself 
with the thought that the 128k 
B+ is probably more software- 
compatible than the Master series; 
at least one can still transparently 
load soft-key definitions, etc, in 
the usual way. 

PS: Has Acorn been taking 
lessons from Amstrad? 

Paul F Tolson

WHY NO SUPPORT 


FOR THE 6502? 

Sir, 1 am writing to explain my 
frustration at Acorn’s range of 
product. At great expense (since I 
was still at school) I bought a BBC 
B three years ago. Unlike many 
others, I am a serious programmer 
and was disgusted by the Beeb’s 
low memory capacity. The 6502 
second processor was therefore 
the next logical purchase. The 
support for this product from 
Acorn was, and still is, abysmal. 
Also, unlike decent machines, no 


monitor or drives were included 
with the BBC B. 

Thank goodness I didn’t up- 
grade to a B+ - an obvious stop- 
gap to keep Acorn afloat. And 
now the new Master Range. Con- 
gratulations Acorn it looks like a 
winner! It also looks as though a 
death warrant has been signed for 
the model B. 

From constant use, my second 
processor now refuses to work, 
and I have the equivalent of an 
elephant on my desk (my Beeb 
and its peripherals). 

Like many other Beeb owners I 
feel cheated and disgusted at the 
lack of support for the 6502 sec- 
ond processor. I am now studying 
for a Computer Studies degree, 
with the aim of becoming a sys- 
tems analyst. So goodbye Acorn - 
my next machine will not be a 
revamped fossil. It will be a genu- 
ine 32 bit, drive and monitor 
inclusive, machine for the 1990s. 1 
have learnt by my mistakes. 

I S Gibson 
Kent 



PRODUCING 


STRIPS 

Sir, Wanting to make a new func- 
tion key strip for a program I was 
writing recently, I turned to Com- 
puter Concepts’ InterSheet. 

The technique proved to be 
simplicity itself. Columns A and L 
of the sheet are set to three charac- 
ters wide, and columns B to K (10 
columns, corresponding to the 10 
function keys) are each set to nine 
characters. The labels needed are 
then typed into the 10 columns, 
using centred justification. By us- 
ing the 105 column display mode, 
the whole key strip can be seen at 
one go, and the layout is thus 
easily checked. 

Finally, the print command / P 
27,64,27,77; is entered, which sets 
the printer (Epson or Canon) into 
elite-sized characters. Columns A 
to L are then printed, and hey- 
presto: the key strip is produced.

HELP ON 


GRAPHICS 

Sir, I am a research student at 
Manchester Polytechnic, my inter- 
est being in computer graphics. 

Could I through your letters 
page ask for a little assistance? I 
would like to hear from any reader 
who’s into computer drawing of 
any kind. I am interested in any 
drawing programs or pictures for 
any purpose whether purely artis- 
tic, graphic or technical. 

The work could have been car- 
ried out on a commercial package 
and be black and white or colour, 
then dumped to plotter or printer. 
I would also be interested in soft- 
ware designed by individuals, or 
any recommendations readers 
might make about any particularly 
useful programs or utilities. 

To finish on a high note: I very 
much like the new magazine de- 
sign and layout, and the high 
standard of editorial content. It 
appeals to a wide readership, and 
also to the continuing newcomers 
to computing (no, I’m not 
crawling!).

INVALUABLE 


SOFTWARE 

Sir, There are many useful engi- 
neering software and hardware 
developments taking place in such 
subjects as structures, electronics 
and graphics in places like 
Harwell, Sussex University, Not- 
tingham, Kings College, etc, 
which to the serious user could be 
invaluable. 

As a regular Acorn User reader, 
I have not come across a survey of 
available software in this category. 
Also, the modem/mainframe ac- 
cessibility to these programs could 
be a boon in the future. Can Acorn 
User advise where a comprehen- 
sive list of available programs can 
be found? 

T Williams 

Sussex 

We do not know of such a list, 
but would like any readers who 
are aware of such to send us in 
one, or let us know where it can 
be found. 

The news pages do try to 
cover software of this kind, and 
we actively encourage people 
to pass information through 
our free ad and £10 ad pages - 
not to mention setting up a 
user group.

LETTERS 




SPEAK TO ME 


PLAINLY 

Sir, I am a relative newcomer to 
computing and to Acorn User but I 
don’t believe I’m a complete dope! 
However, on reading some of the 
March issue I begin to wonder. 

Take ‘Master Work. Our tech- 
nical editor takes the lid off the 
simplest of Acorn’s new series of 
micros’. I’m OK until the para- 
graph about the Break key - I’d 
love to be able to turn mine off 
and I suspect that many other 
owners would too. In the next 
sentence I’m floored because I 
don’t know about the ‘software 
key’. Presumably this is *KEY 10 
but it’s hardly calculated to endear 
me to your technical editor. 

On page 74 I’m invited to read 
about the memory map and study 
‘figure 1’. As this is two pages 
away I need a second copy of the 
magazine - if the photo on page 
74 was swapped with figure 1 the 
problem would have been solved. 
Problems with the layout of arti- 
cles are a regular occurrence in 
computer publications. 

Lastly, can I make a plea for 
plain English? Each edition con- 
tains a wealth of (I presume) use- 
ful information but it’s written in 
jargon. I believe most areas of 
computing can be explained in 
words of two or less syllables. I 
enjoy reading Acorn User (some of 
it anyway) so please accept my 
criticism in the constructive spirit 
in which it is intended. 

Brian Bowell 
Mid Glamorgan 


UNFAIR 

CRITICISM 

Sir, I was disappointed to see part 
of a letter of mine which was 
published in November’s issue of 
A corn User quoted by Beebug / 
Beebugsoft in an attack on you. 

My original letter to Acorn User 
was edited and had the full text 
been published readers would 


have seen that my rebuke related 
to a few specific articles rather 
than Acorn User as a whole. 

In fact Acorn User is still my 
favourite even though I subscribe 
to Practical Computing , , Personal 
Computer World and Beebug. I’ve 
subscribed to both Beebug and 
Acorn User since their beginnings. 

When my truncated letter was 
published n November 1985, I 
had intended to write to congratu- 
late Acorn User on its content. I 
regret not having done so as 
Beebug has now published two 
small quotes from my published 
letter as its response to some valid 
criticism appearing in Acorn user. 

I don’t want to take sides but if 
one compares a typical issue of 
Beebug with Acorn User , the differ- 
ence in size and presentation of 
content is staggering. 

As a member of a ‘a totally 
independent user group’ (Beebug 
page 2, issue 1, April 1982) one 
noticed the gradual dropping of 
the original aims so admirably 
expressed in the first issues. 

Beebug Publications Ltd, 
Beebugsoft Ltd and PMH Mailing 
Services Ltd gradually made their 
presence known. After a while the 
turnover must have exceeded £\ 
million annually if one adds in the 
income from subscriptions, soft- 
ware, distribution deals with High 
Street multiples and Computer 
Concepts, the Electron side of the 
business, hardware sales, advertis- 
ing, etc. 

As a ‘member’ I had often 
wondered why discounts obtained 
from suppliers were never fully 
passed on to the other members in 
the form of lower prices. In fact, 
Beebug' s own hardware prices al- 
ways seemed to be near or at the 
maximum recommended price. 
There are dealers selling the same 
or very similar items at lower 
prices and some of them advertise 
in Acorn User. 

The members’ 25 per cent soft- 
ware discount is smaller than the 
trade discount at which 1 can 
usually purchase some of the ex- 
cellent Beebug products. 


Is it too late to revitalise the 
original aims of the ‘Independent 
National User Group for the BBC 
Microcomputer’ which, inciden- 
tally, on its May 1985 cover pro- 
claimed itself to be ‘Britain’s Larg- 
est Computer User Group. 
Membership exceeds 30,000’? 

Finally, may 1 assure everyone 
that I am not ‘disgruntled readers’ 
but merely one person, despite 
what Beebug printed.

THE EPSON RX/FX/KAGA 
PRINTER COMMANDS 
REVEALED 

So you bought yourself a new printer, because 
the salesman in the shop showed you how clever 
it is and impressed you with all sorts of printouts 
to show its capabilities - he may even have 
offered you a special price. 

However, now that you have got it home and 
connected it to your BBC microcomputer, you 
are wondering how to make it perform these 
magical tasks. The manual seems to give no 
clues, and when you type in the example 
programs, the computer throws the LPRINT 
statements back in your face. 

Now what do you do, when this £400 piece 
of high technology refuses even to move its 
head, and you have stayed up until 2 in the 
morning with copious supplies of coffee, 
desperately trying to print something out. Once 
again, Watford Electronics comes to your help 
with our new book entitled THE EPSON 
FX/KAGA PRINTER COMMANDS REVEALED . 

This book describes in plain, easy to 
understand English, how to use and make the 
most of your KP810, Canon PW1080A or any 
Epson FX80 compatible Printer with the BBC 
Micro, both from Basic and Wordwise. 

It describes in detail how to obtain the 
maximum in graphics capability from your printer 
and includes full indexes allowing you to cross 
index the numerous commands. Every command 
is explained in detail, with an accompanying BBC 
Basic program and an example of its use from 
Wordwise. 

Superb Value at £5.95 (No VAT)

WATFORD'S & ACORN'S 
SINGLE DENSITY DFS 


Watford s popular and widely acclaimed DFS has now been available for three 
years, and has gained a large following amongst serious users of the BBC 
Micro. Owners of Acorn or any other standard DFS can upgrade to our 
” Ultimate " DFS merely by replacing their DFS ROM. See below for this 
upgrade. (P.S. Watford's highly sophisticated DFS is fully compatible with 
Acorn DFS).

instructions £47 

• A corn 's DFS Kit complete £47

WATFORD'S DOUBLE DENSITY 
DFS INTERFACE 

The DDFS from Watford Electronics represents a new standard in DFSs for 
the BBC micro. This is a double density version of our popular single density 
DFS, and combines all the features of this powerful DFS with the advantages 
of a system that g:ves 80% more storage per disc in double density mode. 

P S. - Please note that not all DDFSs are capable of providing either the full 
80% storage increase, or of allowing a file the full size of the disc - Ours 
allows both of these I Operates both in Single & Double Density modes. 

The typical piece of games software these days is provided upon a protected 
disc. In order to work on any double density system (including the others on 
the market) a protected piece of software needs to make calls through the 
OSWORD &7F routines. To ensure compatibility, the Watford DDFS features 
probably the most comprehensive and powerful 8271 emulation ever written 
for a double density system. 

PRICES 

• Complete DDFS Kit incl. fitting instructions £46 

• DDFS Manual (no VAT) £6.95 

• We will exchange your existing Single Density 

DFS Kit for our DDFS Unit at £35 


Watford Electronics DDFS PLUS 
for the BBC B Plus 

Watford Electronics was the first company to produce a serious alternative 
Disc Filing System (DFS) for the standard BBC micro. Since then, we have 
been refining and advancing this sophisticated product right up to today. 

Now WE'VE DONE IT AGAIN; Watford proudly presents the Double Density 
Disc filing system for the BBC B + , with all the advantages of the advanced 
Watford DDFS available on the new BBC B + DDFS. 

Acting as a powerful alternative DFS to Acorn's '1770 DFS' supplied with 
the BBC + , this superb addition to any BBC+ greatly enhances it's 
performance with a simple fitting operation. 

DDFS PLUS incorporates all the features of the Watford’s popular DFS & 
DDFS for the BBC B, (at the same time retaining full compatibility with Acorn 
DFSs). plus it has the following extra features; 

Automatic density selection - Full single and double density operations - 
Extremely powerful and comprehensive OSWORD &7F emulation - Any file 
can be full size of disc - Density of last access assumed for speed - 
Automatic 40/80 stepping swapped on error - All Acorn s extra disc 
commands implemented. 

As you can see from the above information. Watford's DDFS for the BBC+ 
is far more sophisticated and well thought out than the standard. Take any 
disc produced by any Watford DFS from the standard BBC and catalogue 
straight off with no problems. 

Unlike the Acorn 'ADFS', our DDFS+ system is just as easy to use as the 
standard DFSs, with no new complex concepts to have to learn. The features 
within our DFSs have been constantly enhanced over a period of three years 
during the time that they have been released; significant attention has been 
paid to feedback from our customers so that the features offered are carefully 
honed to the requirements of hobbyists and serious programmers alike. 

The Watford DDFS+ is supplied with a comprehensive DDFS manual that 
explains the basics of disc drives. DFSs. etc. Priced at only £30 including the 
manual, the Watford DDFS+ is surely one of THE best buys you could make 
for your BBC B + I 

Join the leaders in BBC peripherals; join Watford Electronics - committed 
to supporting the BBC micro.

COPYHOLDERS 



How often have you been about to type hand written notes into 
your computer when you find that there's nowhere to rest the paper 
or that your notes are resting at the wrong angle to read the type? 
Whether the notes be your latest program or the draft of a new 
trilogy, the new Manuscript Holders from Watford are superb for 
holding your paper at the ideal height and angle to allow you read 
and type in ease and comfort. 

Available in desk resting and shelf clamping versions, these two 
units hold your paper firmly by means of a magnetic ruler and a clip 
grip. 

Mounting to a convenient flat surface, the two joint anglepoise 
Manuscript Holder allows the paper to be positioned at virtually any 
convenient angle whilst only taking up a fraction of the surface area 
that the paper being held does. 

The smaller desk resting Manuscript Holder is useful for the more 
organised desk where the problem is simply holding the paper at the 
right angle. 

Whatever desk arrangement you use, surely you deserve a Watford 
Manuscript Holder! 

Amazing value at only 
Desk Top £10 (carr. £2) 

Angle poise £17 (carr. £3) 




Quality Disc Drives from Watford 


To help you decide which drive is the most suitable for your needs (and your 
pocket!), we have produced the table below. 

The first capacity given in the first column indicates the single density 
capacity. The double density storage capacity is second one, (that within the 
brackets ). All disc Drive type numbers start with the prefix "C". 

The tinting on some of the boxes is used to indicate which Drives are 40 
track and which are 80 track. The 40 track ones are manufactured by EPSON, 
the world famous Japanese company, (non-tinted boxes). The 80 track drives 
are famous MITSUBISHI drives (tinted boxes). 

With two prices in a box (e.g. E295/E299), the first price is for the standard 
drive and the second for the same unit in switchab/e type. Users of either of 
the two Watford DFSs will not need switchab/e drives as their DFS will 
provide software switching for them. 

All our Disc Drives are Double Sided and will operate in both Single 
and Double Density modes. Extensive experience of the usage of disc 
drives suggests that the MITSUBISHI and EPSON drives currently represent 
about the best in terms of speed, reliability and overall ' elegance'' available 
for the BBC Micro. 

Various other "manufacturers'' of disc drives for the BBC micro (more 
accurately, "packagers" label other manufacturers drives with their own 
name). We buy the high quality Epson and Mitsubishi drives in large quantities 
directly from the manufacturers, package them and sell them at "dealer" 
prices direct to the public. 


MYSTERIES OF DISC DRIVES 
& DFS REVEALED 

Are you tired of faulty cassettes, and lengthy loading times? Do you want to 
upgrade your BBC micro to take discs but you get tied up in the plethora of 
jargon surrounding the choice and use of these systems. 

For instance, what is the difference between single and double density 
formats, how can you use a 40 track disc on an 80 track disc drive? What is 
the difference between a DFS and disc interface kit? Should you acquire a 
single Disc drive or twin? What does 48 TPI and 96 TPI discs mean? These 
are just a few of the questions you may have asked yourself and never found 
the answer or maybe you have yet to encounter these questions. 

Now the mystery of buying a suitable interface and disc drive for your BBC 
micro is revealed in Watford’s new book entitled MYSTERIES of DISC 
DRIVES & DFS REVEALED’. It describes in fine detail, yet remaining very 
readable to the beginner, how disc drives operate, the type of interfaces 
available, which type of discs to use on a disc drive and how data is stored on 
the discs. 

£5.95 (Book No VAT) 


3M- DISKETTES 


If you look around the popular BBC micro press, you will find that the prices 
we quote for the top quality, new slimline disc drives are, virtually without 
exception, some of the best around. These prices, coupled with the backup of 
one of the country 's largest distributors of BBC peripherals provides a superb 
deal. 

Unless you anticipate using dual drives in a fully expanded BBC system for 
long periods of time with little ventilation, then we suggest that our range of 
"CL" disc drives without the PSU (Power Supply Unit) would be quite 
adequate: extensive tests within our workshops have confirmed this. All drives 
are supplied complete with a SPECIAL UTILITIES Disc, Cables and Plugs. The 
Drives with power supply have a mains moulded plug for safety purposes. 

( Ideal for Schools & Colleges. All single disc drives with power supply, (i.e. 
CS100, CS200 & CS400S) are supplied in a twin case with twin data cable 
for later inclusion of a second drive). At Watford we anticipate your needs of 
tomorrow not just today! 

When using a BBC Micro, most people find themselves preciously short of 
space. The Watford's BBC Micro Plinths form an ideal way of recovering some 
of this space; your BBC, disc drive and Monitor can all occupy the same 
vertical footprint and still be comfortably situated. Some of our competitors 
offer disc drives built into plinths, but these aren't as sensible as you might 
think. With a Watford Plinth, your disc drive is mounted vertically at one side, 
leaving a very valuable area directly in front of you for such useful items as 
spare discs, pen and paper, reference manuals, etc. Follow the trend with 
Watford Plinth.

EPSON NLQ ROM

DUMPOUT3 


ROM MANAGER 



Harness the full potentials of your Epson RX & 

FX Printers. Impress your friends and business 
colleagues with the quality of your letters and 
printed material with Watford's very simple to 
use EPSON NLQ! (Near Letter Quality) ROM. 
Suitable for FX80, RX80, RX80F/T, FX100.

modifications from BASIC. WORDWISE. VIEW 
(with NLQ DRIVER) or virtually any other

THE NLQ DESIGNER 

KAGA KP8 10/9 10 and Canon PW1080are two 
superb printers, as our many thousands of 
satisfied customers would surely attest to. One 
of it's particularly strong points is the NLQ option 
that it offers; perhaps one of the more weaker 
points is the effort required to design your own 
custom NLQ font. 

Well the solution is here NOW in the shape of 
Watford's NLQ DESIGNER ROM! For the BBC 
Micro. This powerful piece of software allows 
easy design and entry of a full NLQ font, with 
further fonts recallable from disc. Once a font 
has been programmed with the versatile NLQ 
DESIGNER, it can be saved to disc, downloaded 
to your Kaga (or Canon) printer, or even 
programmed into an EPROM (given the 
appropriate hardware) and then plugged directly 
into your printer so that it is available 
immediately when you turn it on. Downloadable 
Fonts require 6264 RAM chip fitted. 


A 40/80 track format disc containing 3 example 
fonts is included in the package. 

(P.S. This ROM is not suitable for Epson printers 
as they don't normally have NLQ ability. Keep 
reading our adverts though - work is in 
development!) 

• NLQ Designer ROM & FONT Disc £25 
• Kaga Individual FONT ROMs £15 



A highly sophisticated screen dump ROM. This 
has to be the most flexible and powerful screen 
dump ROM yet produced for the BBC micro. It 
will put on paper anything you see on the 
screen, including all Mode 7 facilities etc. We 
have to admit that there is one facility that we 
cannot replicate - if anyone can supply flashing 
ink we would like to know! 

The ROM also provides window setting utilities 
and two new OSWORD calls that allow mode 7 
graphics pixels to be read and plotted using the 
standard graphic co-ordinate system. The latest 
version includes a graphic dump trigger for 
dumping screens from games whilst they are 
running. 

Two commands are used to operate the dump 
routines: 

•GIMAGE - This provides a full graphics dump 
of any graphics mode, plus modes 7 and '8'. 
There are many optional parameters but you 
need only specify the parameters you wish to 
change. 

Features available include: 

• Vertical and horizontal scaling through all the 
graphic modes and mode 7 

• Rotation of the image produced through 90, 
180 and 270 degrees 

• Left hand indentation setting 

• Screen dump window definition 

• Colour grey scaling 

• Two tone fast dump 

• Special colour mask 

• Mode 7 contrast expansion 

• Mode 7 contiguous dump 

• Key triggered dumps 

• User port switched dumps 

What does the independent press say! 

Practical Electronics, May 1985 
"The Dump Out 3 ROM from Watford 
Electronics represents one of the most 
sophisticated types of printer dump utilities 
available for the BBC Micro . . 

"an extremely sophisticated and powerful dump 
utility”. 

“VERDICT - Dump Out 3 ROM has all the 
facilities which you are ever likely to need for 
producing printer dumps. The facilities available 
work extremely well and if printer dumps are 
something which you require, then this ROM can 
be recommended to help you to get the best out 
of your dot matrix printer”. 

The Micro User Feb. 1 985. 

Well, here is that winner "I 

'provide(s) some rather sophisticated screen 
dumps. Producing high resolution paper copies of 
graphic screens in any (graphics) mode will be 
the major reason for buying this ROM, and this 
is where Dump Out 3 performs PAR 
EXCELLENCE”. (Our capitals for their italics.) 

The versatility of *GIMAGE (the graphics dump 
command) when using these parameters is 
amazing. Pictures of almost any size, shape, 
contrast or distortion may be produced without 
the need for a reducing photocopier or trick 
photography”. 

"Without reservation I wholeheartedly 
recommend the Dump Out 3 ROM as the 
ultimate screen dump facility for the BBC micro. 

It is easy to use yet highly versatile, and caters 
for all BBC screen modes in multitone high 
resolution printing. Whole, partial, rotated and 
scaled screens may be dumped to almost any 
BBC compatible dot matrix printer (see our list at 
the end of this advert). At £25 it must represent 
excellent value for money and surely cannot be 
beaten”. 

Designed for use with the following printers: 

CP80, GP80/1 00/250, CANNON. STAR, 
KAGA/TAXAN, NEC, SHINWA CP80. GEMINI, 
EPSON MX/RX/FX, LPVII, NEC PC8023, 

DM PI 00/200/400. Mannesman Tally etc. 

Price including comprehensive manual 

£25 



Probably the most powerful way of expanding 
the BBC micro is from the use of Sideways 
ROMs. One problem faced by the avid ROM 
collector is that of ROM command clashes. The 
solution is very simple in the form of the ROM 
that "Provides comprehensive management of all 
your installed ROMs”. (Quote from BEEBUG 
November '84.) 

Basically, ROM Manager offers you the ability 
to turn off any installed ROM, or to send any • 
command to any specific installed ROM. It is 
said that imitation is the sincerest form of 
flattery - Acorn's BBC Plus features many of the 
abilities of this powerful ROM. 

Many more facilities available.

BEEB PRINTER ROM 



Makes Printing Childs Play ~ 


This utility ROM is designed to simplify using all 
the facilities of your printer. It has many 
facilities: 

★ Selection of printer modes such as underline, 
font and size is by 'Single Key' operations. 

★ From Wordwise, a single number following 
OC will select a mode rather than a long and 
incomprehensible string of control codes. This 
makes using your printer with Wordwise much 
more convenient. 

★ When using Basic (or other languages) you 
can have control over the formatting of the 
output to the printer in the style of a 
wordprocessor. You can define page top. bottom 
and side margins etc. with intelligent page skip 
for binders an option. All supported printers will 
now respond to form-feed etc. commands. 

★ User defined characters are printed as you 
see them on the screen so that non-standard 
characters are automatically printed out correctly. 

★ Commands select the options for the 
following printers: 

GP100, STAR, NEC, MX/FX, KAGA, 

LP/VII/DMP1 00, DMP200. 

Operates with either parallel or serial interfaces. 

★ Supplied with a 50 page manual that is very 
comprehensive and easy to follow. Please specify 
printer type when ordering so that we can send 
the correct function key strip.

DIAGNOSTICS 

DISC 



The BBC micro is a very complex machine and 
thus diagnosing a fault can be very difficult. Until 
now, the only way to discover the nature of a 
fault was either to find a competent friend with a 
large degree of patience or to find your nearest 
dealer and pay him to find out what is wrong. 

At Watford Electronics, we realise how difficult it 
can be when faced with a problem, finding 
yourself a long way from your nearest dealer, or 
even just uncertain about your Beeb's health, but 
not wanting to waste time and money taking it 
to be looked at. 

The solution to these problems is here now, in 
the form of the Watford's Diagnostics Disc. This 
excellent utility is specially designed to test out 
the following areas of your Beeb: 

RAMs, ROMs, ULAs. Sound, Keyboard, Disc, 
RS423, ADC, User Port, Printer Port, Cassette, 
Joysticks, Speech, Disc Drives, 6502 and Z80 
2nd Processors. 


This utility is an invaluable aid for all those who 
take the reliability of their system seriously. A 
comprehensive manual provides full operating 
details and a list of possible causes and remedies 
for any faults that you may find along the way. 
The package also enables a permanent 
equipment and service record to be maintained.

ROM-SPELL 

"way ahead of any competition" 


ROM-SPELL is probably THE most advanced and 
fastest spelling checker available for the BBC 
Micro. Printed below are some extracts from a 
recent independent review (A&B Computing Nov. 
85), which we feel sure will convince you that 
this is THE only spelling checker worth 
considering. 

The editing system is very neat and simple, 
instead of replying to queries and beeps all of 
the time . . 

The other feature which places ROM-SPELL 
way in front of any competition is the ability to 
examine the user dictionary, so any spelling 
mistakes that have found themselves on the disc 
can be examined and taken out if necessary ". 

. . that it is compatible with many of the 
popular word processors on the market is a good 
indication that ROM-SPELL is going to be a very 
popular product indeed". 

. . ROM-SPELL is by far the best spelling 
checker for the unexpanded BBC B (with or 
without word processor). It boasts features which 
are hard to find on conventional spellcheckers on 
CP/M and MSDOS, namely Spellstar and has a 
speed/performance ratio of roughly the same as 
its CP/M cousin. The difference is that the CP/M 
version would cost the best part of £500”. 

. . and with such vital house keeping features 
as an ambiguous word checker, the ability to edit 
the user dictionary, a comprehensive manual that 
is both easy to read and actually ENJOYABLE to 
learn from. ... I feel confident that ROM-SPELL 
will woo the word processing public with no 
problems at all". 

Don't settle for less, Buy the best. 

ROM-SPELL costs only £25

BEEBMON 

BEEBMON is the most powerful and versatile 
machine code monitor from Watford Electronics. 
BEEBMON offers some superb features specially

debugging machine code easier; indeed 
BEEBMON is probably the only product with 
sufficient power to aid in the debugging of such 
complex pieces of software as a DFS. 

Offering a total emulation mode, BEEBMON can 
be used to single step through code anywhere in 
memory. All breakpoints are emulated and the 
workspace is totally relocatable, allowing for the

ROM/RAM 

CARD 

A must for all serious users 



Watford Electronics announced the first ever 
commercial ROM board for the BBC micro, the 
Watford Electronics 13 ROM Socket Board 3 
years ago. Following the success of this board, 
we have designed what probably represents the 
ultimate in expansion boards, the new Watford 
Electronics ROM/RAM board. This highly 
versatile and sophisticated board represents the 
latest in "2nd generation" sideways ROM 
technology for the BBC micro, designed to 
satisfy the serious BBC user. 

• NO SOLDERING required to fit the board. 

• NO overheating problems. 

• No User Port corruption (avoids problems 
with the mouse, modems, Eprom Programmers, 
etc.) 

• Fully buffered for peace of mind. 

• Firm mounting in BBC micro. 

• Compatible with ALL BBC micros (not BBC 
Plus). 

• Total number of ROMs increased from 4 to 8. 

• Up to 8 banks of sideways RAM (dynamic). 

• Option for 16k of Battery backed CMOS RAM 
(CMOS RAM needs one ROM socket). 

• Write protect for ALL RAM. 

• Master write protect for all sockets. 

• Read protect for CMOS RAM (ALLEVIATES 
crashes during ROM development). 

• Separate RAM write register (&FF30 to 
&FF3F). 

• Automatic write to currently selected RAM 
socket for convenience. 

• Can run ANY BBC ROM. 

• FREE utilities disc packed with software. 

• Compatible with our DDFS board, 32k RAM 
Card, Delta Card, sideways ZIF, etc.

SYSTEM (similar to the popular Watford DFS). 

• ROM to RAM load and save facilities. 

The SFS (Silicon Filing System) can utilise up 
to the full 128k of RAM (with the SFS in any 
paged RAM) as a SILICON DISC. This behaves 
as a disc drive, with all the normal Watford DFS 
features (including OSWORD &7F for 
ROM-SPELL, etc.) to provide an environment 
that looks like a disc but loads and saves MUCH 
faster. 

The ROM/RAM Board plugs into the 6502 
CPU socket. This leaves free all the existing 
ROM sockets, which can still be used normally. 

Any ROM that can be plugged into the BBC 
micro's own ROM sockets may be used in the 
ROM/RAM Board. 

The ROM/RAM Board is supplied with all 
ordered options fitted as standard. Upgrade kits 
(with full instructions) are available for all of the 
options, should the user wish to upgrade in the 
future. Please write in for further details.

SHADOW RAM 
Printer Buffer 

Expansion Board 



A MUST FOR WORD PROCESSING 


Watford Electronics now brings you the latest 
state-of-the-art MEMORY EXPANSION BOARD 
for your BBC microcomputer. Just plug the 
ribbon cable into the 6502 processor socket, and 
fit the compact board inside the computer. 
Immediately you will gain not 16K or even 20K, 
but a massive 32K of extra RAM!!! 


• IMPROVE your WORD PROCESSING system, 
whether disc or cassette based. Don't wait for a 
slow printer - type in text while printing. TWO 
JOBS DONE SIMULTANEOUSLY and £100+ 
saved on a printer buffer. 


• "VIEW" Wordprocessor users can now type in 
text in 80 columns and have up to 28,000 bytes 
free - 5 times as much as normal. 


• In WORDWISE (or WORDWISE-PLUS). 
preview in 80 columns with the full 24K of text 
in memory. This superb product is recommended 
by Computer Concepts for use with both 
Wordwise and Wordwise Plus. We 
wholeheartedly agree with this commendation. 


• Combine GOOD GRAPHICS and LONG 
PROGRAMS. Use the top 20K of the expansion 
RAM as the screen display memory, leaving all 
the standard BBC RAM free for programs. 
Benefit from MODE 0/1/2 graphics and 28K of 
program space. 


• Use 12K of the expansion RAM as a 
PRINTER buffer for PARALLEL or SERIAL 
printers, sound channels, RS423 etc. Only a 12K 
printer buffer can be used in Wordwise or 
Wordwise Plus due to the way in which they are 
written. Print large text files while running long 
graphics programs and have all your buffer 
options available as well 

(*FX1 5,2 1 ,1 38,1 45.ADVAL etc). Only 12K Buffer 
can be used in Wordwise or Wordwise + 
because of the way these softwares are written. 


• Ensure COMPATIBILITY with a vast range of 
hardware (including Watford & ATPL ROM 
boards, double density boards, second 
processors), and software (including BASIC, 
TOOLKIT, VIEW. WORDWISE (1.20+), 
WORDWISE-PLUS). This is because our board, 
unlike those of our competitors, is connected to 
the computer by a ribbon cable. 


• Achieve EASY OPERATION with ROM based 
software. A large range of commands is available 
for machine code and BASIC users, including 
some useful *HELP messages.

EPROM PROGRAMMER 



The Watford Electronics' EPROM programmer for 
the BBC micro is a high quality self contained 
package. Programs all popular EPROMs from 2K 
to 16K: 2716, 2516, 2532, 2564, 2764 and 
27128. All manufacturers' specifications have 
been followed to program EPROMs at the 
correct speed - wrong timings could destroy 
your EPROMs. The unit has its own power 
supply so does not put heavy loads on the BBC 
power supply as do some other units. Connects 
directly to the 1MHz bus following all Acorn 
recommendations on addressing and bus 
loadings. 

SOFTWARE PACKAGE 

The software is supplied on an EPROM which 
plugs into the Micro and is instantly available 
with a single command (no time wasting as on 
Cassette/disc loading). It is a fully purpose 
designed and ingegrated package to simplify 
ROM development. The system is menu driven 
with many prompts to avoid any accidents. 

Software facilities include: 

Load File - Save File - Down Load EPROM - 
Program EPROM - Verify - Blank Check - 
Editing of memory contents prior to 
programming. 

Also included is an automatic system to allow 
Basic programs to be put in EPROM and 
accessed through the # ROM filing system. More 
than one program may be put in an EPROM. All 
these facilities and more are explained in the 
comprehensive and clear 1 5 page manual. 

SPECIAL OFFER £69 (£3 carr.) 


TEX EPROM ERASERS 

EPROMs need careful treatment if they are to 
survive their expected lifetime. Over erasure of 
EPROMs very rapidly turns them into ROMs! The 
TEX erasers operate following the manufacturers 
specifications to give the maximum possible 
working life by not erasing too fast. We use 
these erasers for all our own erasing work. 

• ERASER EB - Standard version erases up to 

16 chips. £28 (carr £2) 

• ERASER GT - Deluxe version erases up to 

28 chips. Has automatic safety cut-off to switch 
off the UV lamp when opened. £30 (carr £2) 

• Spare UV tubes. £9 


BEEB 

VIDEO DIGITISER 



Using any source of composite video (colour or 
monochrome) and the Watford Beeb Video 
Digitiser, you can convert an image from your 
camera into a graphics screen on the BBC Micro. 
This uses the full graphics capacity of the BBC 
micro in modes 0, 1 or 2. The video source may 
be a camera, video recorder or television, and is 
connected via the video output socket. 

Images produced can be compressed, stored to 
disc, printed on an Epson compatible printer, 
directly used to generate graphics, analysed for 
scientific and educational use or converted to 
other formats e.g. Slow Scan TV or receiving a 
picture from a remote camera using a modem. 
The output from the digitiser exactly matches the 
graphics capability in each mode, with up to 8 
levels of grey in mode 2. The unit connects into 
the User Port and automatically scans a 
complete picture in 1.6 seconds. 

Both the black and white levels can be adjusted 
manually for the optimum picture, or switched to 
automatic for unattended use. The image 
produced can be reversed if necessary. 

Full controlling software is supplied on a normal 
sideways ROM and this is easily accessed via 
additional # commands. The package is designed 
to allow easy input of complex screens and give 
full access of the data to the user. Once on the 
screen, the image can be used as a normal 
graphics screen, allowing any of the usual 
graphics commands in BASIC or other ROM's to 
work on it. 

A special print dump routine is included with the 
driver programs. This is specially designed to 
produce a fast, correctly proportioned picture, 
with reduced 'contouring ', resulting in an 
accurate reproduction of the original image. 

Detailed examples of driving this unit from 
BASIC or other languages are all provided in the 
extensive manual supplied. 

£110 (Carr. £3) 

(Price includes: Digitiser Unit, Software in ROM 
& a Comprehensive Manual) 


Magazine Maker 

(As seen on TV) 

A combination of the AMX Pagemaker and 
Watford’s Beeb Video Digitiser. 

Using any video that provides a composite 
signal and the digitiser, images from a camera or 
TV can be converted into a graphics screen on 
the BBC Micro. 

They can then be used within AMX Pagemaker 
to illustrate magazines or newsletters - in fact 
anything that needs to be created on A4 size paper. 

With Pagemaker's many features, a variety of 
pictures can be composed - the only limit being 
the imagination. 

Pictures can be doctored using Pagemaker's 
graphics option to produce any number of effects. 

Text can be formatted around the digitised 
photo on screen using the facilities available, 
which include 16 typefaces, character and 
pattern definer, text formatting and the ability to 
load in wordwise and viewfiles plus much more. 

Once created the picture can be printed out. 

The Magazine Maker is suitable for any use 
that requires illustrated documents. 

Complete Package £129.00 (carr. £3)

DATAGEM 

Now compatible with Watford DFS's 

Long hailed as the most comprehensive and 
powerful database for the BBC, and now 
becoming a legend in its own right, DataGem 
has been significantly reduced in price now that 
development costs have been recovered by 
Gemini. Whether you have a single 40 track 
drive or a Winchester hard disk, this system will 
make use of ALL your disk space, treating up to 
4 drive surfaces as ONE CONTINUOUS FILE. 
Much has been made and exploited of 
DataGem's superb selective searching capability, 
and together with its unmatched mathematical 
powers, the system provides a really professional 
database for use in the home, office or school 
that will harness the full power and potential of 
the BBC micro. 

AMATEURS & PROFESSIONALS 

For newcomers to databases as well as seasoned 
users, DataGem represents an ideal starting 
point. Structuring your file and layout couldn't be 
simpler using DataGem's on-screen painting' 
format. You can have up to 62 fields or data 
items wherever you want them on a scrolling 
120 x 120 card. Colours are all definable, and 
field data and field titles may be separated if 
required. Data entered may be stored in up to 8 
tiers or levels', as well as within the whole 
database file. Scan one level or the whole 
database for records that match your search 
parameters, and place them in another data level 
for later manipulation. DataGem also boasts 
limited facilities for producing data merged 
letters, and may be configured as a 62 cell 
spreadsheet.

wide range of useful facilities for the busy person

forgetfulness and ensure that your time is 
organised, you know what you have to do and 
when, you don't forget bills or birthdays, and you 
are reminded constantly of urgent matters. 

LBO was written by two graduates in 
Computer Science from Exeter University in 
consultation with a lecturer in Cognitive 
Psychology. It has been very cleverly researched 
and programmed and is confidently 
recommended by Gemini as a very superior 
program for the very superior BBC micro. 

Features include: 

• Automatic reminder of entries overdue for 
attention. 

• One week's advance notice of forthcoming 
events. 

• Urgent notice board. 

• Creation of categories of entries; e.g. bills, 
birthdays, letters to be written, notepad etc.

day.

related word or part word.

events.

1999! It can handle literally hundreds of 
multi-line messages, as many as you are ever 
likely to need. Despite the very wide range of 
facilities offered, this professional program is 
VERY easy to use and requires absolutely NO 
knowledge of computers. A vital aid to your 
everyday life, LBO is GREAT FUN TO USE!

SURGE PROTECTOR Plug 


Fitted in place of your normal mains plug, this 
device protects your equipment against mains 
surges. Nearby lightning strikes, thermostats 
switching and many other sources put high 
voltage transient spikes on to the mains. This 
can lead to data corruption in memory and on 
disc and can result in spuriously crashing 
machines. A must for every computer user.

PLINTHS FOR BBC MICRO 
AND PRINTERS 




Manuals 


Protect your computer from the weight and heat 
of your monitor. The BBC micro plinths have 
slots for maximum ventilation. The single plinth 
is suitable for a BBC and monitor, whilst the 
double height version provides enough room for 
our stacked or side-by-side dual disc drives or 
TORCH Disc pack, to be placed in the centre 
section. If you use our stacked drives, the 
remaining space can be used for further 
peripherals e.g. Speech Synthesizer, EPROM 
programmer or simply stationery. The computer 
slides neatly in to the lower section allowing 
easy access to remove the lid. The printer plinth 
is equally sturdy but without the cooling slots. It 
allows for access to the paper from the front as 
well as from the rear, (a facility not often 
thought of in similar products) if the paper is 
located beneath the plinth. This is a very 
convenient way to work especially if your work 
area is not deep enough to take the printer and 
paper separately.

enable the user to learn to influence his own 
state of mind. 

BIOGRAM is FUN and EASY to use, just

several ROMs with just one command. ROMs can be specified 
their socket numbers or their title or even abbreviations of the 
title. 20 commands are available, please send for full details. 

As a bonus feature for anyone who has files they want to keep 
from prying eyes, ROM master contains the commands 
SCRAMBLE & UNSCRAMBLE which will encrypt or de-encryp 
file based on an entered password. The encryption used is hig 
sophisticated so unless you know the correct password the file 
cannot be read. _ . . _ _

ITS QUICKER 
BY TUBE 

Speed up data transfer across the Tube by including software in the BBC micro 
and second processor to enable them to communicate with each other 


T his article forms the final part of a 
discussion of extensions to the 6502 
second processor Hi Basic. The first 
part, in March, described an improved 
and extended assembler to take full 
advantage of the more advanced 6502 chips 
'i now in use. 

< The 6502 second processor for the BBC 
Z micro is clearly a very useful addition to the 
* system. It allows the use of a more powerful 
p 6502 chip, faster programs and significantly 
% more RAM. It is connected to the BBC micro 
d through the Tube interface which allows both 


microprocessors to share the work by running 
in parallel. 

There are some fairly unsophisticated facili- 
ties provided for transferring bytes across the 
Tube which are documented in the user guide. 
OSWORD calls 5 and 6 allow the second 
processor to read from, and write to, the BBC 
micro motherboard, and OSBYTH calls &92 
to &97 read from, or write to, the mapped 
input/output pages &FC, &FD and &FE. 
These calls, however, only transfer one byte at 
a time. Given the speed of operation possible 
for the Tube operation (up to 100,000 bytes/ 


second), this speed of transfer is miserably 
slow, at about 1500 bytes/second. So we need 
faster operation in both directions. 

The programs presented here set up such a 
system and allow it to be incorporated into a 
Basic program by assigning the unusued 
keyword token &CF to the introduced 
keyword ‘TUBE’. A complete mode 2 screen 
(20,480 bytes) can be transferred in just over 
210 milliseconds in a Basic program. The 
CALL keyword function is also extended to 
allow calls to be made from a Basic program in 
the second processor to machine code in the

JOYSTICKS— 

THE COMPLETE SOLUTIOE 


DELTA 3B TWIN- BBC B or ELECTRON PLUS 1 £19.95 

A direct but improved alternative for the original ACORN 
joysticks, with 2 joysticks wired to one plug. As with all our 
joysticks they have the fast action sprung to centre return 
of the steel shafted nylon covered joystick. The light action 
makes them ideal to hold and the 3 fire buttons allow left 
or right-handed use. 

DELTA 3B SINGLE- BBC B or ELECTRON PLUS 1 £1 2.00 

A single joystick that in some ways can act as two. The 
custom made special "low noise" potentiometers are 
wired so that it will work as a left hand or right hand 
joystick. It can even run some programs written for two 
joysticks and has the fire buttons of both. 

DELTA 14B-BBCB £14.95 

Our original ACORN/BBC handset. The sdme super light 
joystick, but the long life buttons, which have been video 

g ame tested for many years, increased to 14 in number. A 
ELTA 14B/1 is needed to run the keypad but d 14B on its 
own will work as a joystick and fire buttons, so you can 
always add the 14B/1 to it later. 

DELTA 14B/1 for use with 1 or 2 DELTA 14Bs £14.85 

DELTA DRIVER CASSETTE £5.95 

The A/D/USER PORT interface box. This aives simultaneous 
access to both the analogue port, for the joystick part and 
the user port, for the keypad. Two handsets can be 
plugged into the box giving a total of 24 user definable 
keys. 

Full instructions are provided to include the keypad in your 
own programs even in BASIC or for the non-programmer a 
DELTA DRIVER cassette is available with keyboard to 
joystick/keypod conversions and keypad set up programs. 

DELTA 3S (for ELECTRON with switch joystick interface) £12.00 

For an ELECTRON with a switched joystick interface (Not a PLUS 
1 ) this gives you the same delightful light, fast action of the 
DELTA joysticks but fitted with a 9 way D plug as per Atari, 
Commodore, etc. and will run on First Byte interface or similar. 

DELTA ASC/B FOR BBC, DELTA ASC/E FOR ELECTRON PLUS 1 

(not illustrated) £9.95 

This little box plugs in series with your analogue joystick to 
alter its characteristics simply by using a switch. In one set 
up the joystick will act like a switched joystick, i.e. a slight 
movement will act as if the joystick has been pushed hard 
over. In the other mode the joystick only covers the centre 
half of the A/D converter so that it takes twice as much 
movement to give the same effect. This makes it much 
easier to make delicate adjustments to programs like 
flight simulators. 

DATAPAD 16B £39.95 

A commercial spec. 16 way keypad. Full travel 
mechanical keys with double shot moulded keycaps 
mounted in a low profile metal case. The keys are marked 
with calculator legend, but the software included allows 
the pad to be defined as any keys, including function keys 
or single byte VDU commands such as PRINTER ON/OFF. 

No tampering with the computer as it fits onto the user 
port. 




UTILITIES 


BBC micro’s RAM or paged ROM. The paged 
ROMs can be selected by an OSBYTE call 
(OSBYTE &A4 or *FX164), making use of a 
previously unused OSBYTE parameter. 

The problem with fast byte transfers across 
the Tube is mainly concerned with letting one 
end know what the other is doing! This is 
satisfactorily solved by including machine code 
at both ends which know what is happening 
and can communicate with each other. 

Tube registers 

There are eight Tube registers at either end, 
four are ‘status’ which indicate whether there is 
a byte waiting to be read (bit 7 set, =1) or 
transmitted (bit 6 reset, =0) in the adjacent 
‘data’ channel. The status bytes are easily read 
by the BIT instruction followed by BPL (bit 7 
tested) or BVC (bit 6 tested) branch instruc- 
tions. The first pair of registers is reserved for 
OSWRCH calls (graphics and text), the second 
pair is used for other operating system calls 
(eg, OSBYTE and OSWORD), and the other 
two pairs for the filing system. The easiest pair 
of registers to use is the one used by the 
OSBYTE calls as this is checked regularly (up 
to 140,000 times/second) by the BBC micro. 

The main byte transfer routines in my 
program use the unassigned OSBYTE code 


164 (&A4). This entails sending a reason code 
( = 6) followed by two data bytes and then the 
code ( = 164) to Tube channel 2. The reason 
code determines the jump address (&500 + 
reason code) in the BBC micro: in this case it 
jumps to the code for OSBYTEs greater than 
159. The two data bytes are interpreted as the 
registers X and Y. The remaining data is sent 

Machine code at both 
ends know what is 
happening and can 
communicate with 
each other 



after this OSBYTE code. If this data is absent, 
the new code at the BBC micro end treats the 
call as a straightforward *FX164 call to check 
the presence of the code or change the ROM 
accessed (see later). 

In either event, the data is redirected from 
the OSBYTE vector (&20A-&20B) to the 


new code. After the byte transfer has been 
completed the second processor continues to 
execute its HiBasic interpreter and the BBC 
micro returns to its idler routine between &36 
and &45 in zero page. 

By choosing this rather indirect way of 
using OSBYTE &A4, the programs avoid 
notifying the second processor end of the Tube 
that OSBYTE has been used. If it was notified, 
it would annoyingly insist on waiting for the 
return byte which would both complicate and 
interfere with the byte transfer process. 

Buffers 

The buffers chosen for the programs perhaps 
need some comment. Locations &57-&8E in 
the BBC micro and &4E-&8F in the second 
processor are free in page zero. 

The BBC micro has an extended character 
set which changes its PAGE to OSHWM 
4- &5FF leaving the first free location as 
&1F0O (disc system) or &1400 (tape system). 
&1F00 is the address chosen for this program 
although other RAM may be used (eg, &A00) 
under certain circumstances. 

The machine code at the second processor 
end has been put immediately below HI MEM, 
to enable it to be saved with the changed 
HiBasic, although again another RAM area

may be more suitable. The fast Tube routines 
may be extracted from the HiBasic extension 
by omitting some of the assembly as outlined 
in the program notes. 

There are two programs on the yellow pages 
to type in which set up the BBC and second 
processor (2P) at both ends of the Tube 
(listings 1 and 2). The specific details as to the 
use of the extensions to the HiBasic are set out 
in the program notes. There is also a test 
program, listing 3. 

Additional Basic keyword 

The keyword we add to Basic is TUBE, used as 
follows: 

TUBEGET BBC-address, 2P_address, 

No_of-bytes 

TUBEPUT BBC-address, 2P_address, 

No_of_bytes 

The new Basic keyword TUBE is used to 
transfer memory contents through the Tube. 
TUBEGET collects bytes (No_of_bytes) from 
the BBC (input/output processor) starting at 
memory position ‘BBC-address’ and places 
them in the second processor starting at ‘2P 
address’. TUBEPUT collects bytes 
(No_of_bytes) from the second processor 
starting at ‘2P_address’ and sends them to the 
BBC (input/output processor) starting at mem- 
ory position ‘BBC_address’. 

The ' TUBE command is tokenised 
(=&CE), as is the GET in TUBEGET. The 
minimum abbreviations allowed are TU.G and 
TU.P (TUBEG and TUBEP are also allowed). 
The syntax indicated above should be used. 

The interpreter expects three numerical 
parameters after the TUBEGET or 
TUBEPUT command which must be separat- 
ed by commas. Real numbers, hexadecimal 


(prefixed by &) and variables may be used. 
There must be a space before the first para- 
meter if it is a variable. If the instruction is 
incorrectly formulated a new error (‘TUBE 
ERROR’, ERR = &60) is produced. 

A certain amount of care is needed in using 
these commands as they will corrupt the 
memory receiving the transferred bytes 
(&0000 to &2000 in the BBC and &0000 to 



Any ROM can be 
read into the second 
processor and any 
machine code routine 
in ROM accessed 


&0800 plus HIMEM to &FFFF in the second 
processor should be avoided). 

CALL&FFxxxx is an extension of the nor- 
mal CALL command. It allows machine code 
calls to the BBC if the address specified has 
&FF in its most significant byte of three. The 
A, X and Y registers and the carry flag are 
copied from the least significant bytes of A%, 
X%, Y% and C% and sent across the Tube to 
a machine code routine (set up by the user) at 
address &xxxx in the BBC micro. The CALL 
releases the Tube immediately, and allows both 
processors to execute independently. As the 
command USR uses the same code, it will not 
operate properly if the high address is used 
here. For example, PRINT USR&FFxxxx 


returns the registers as entered without 
change, but does call the BBC' program using 
these registers. Normal USR and ("ALL opera- 
tions are unaffected. 

New *FX call 

The new *FX call has the following syntax: 
*FX164 
*FX164,X,Y 

where X and Y are numbers. This is used for 
two purposes. As just *FX164 without para- 
meters (or with any parameters except X = 1) 
it simply checks whether the appropriate code 
for these extensions is present at the BBC end 
of the Tube. If not present, the error ‘bad 
command’ (F^RR = 254) occurs. If the code is 
present, no error occurs and &FF is returned 
in the X and Y registers. 

If *FX164 is used with X = 1 (ie, 
*FX164,1,Y), the ROM in the socket indicated 
by Y (the ROM position) is selected (eg, 
*FX164,1,4 selects the ROM in socket 4). 

With a ROM extension board up to 16 chips 
may be selected in this way. This call is mainly 
employed to select the memory used by the 
TUBE and CALL extensions. 

Thus, any ROM can be read into the second 
processor and any machine code routine in 
ROM accessed. 

This *FX call is not used by the operating 
system or DNFS, and is different from that 
used by the Graphics ROM (*FX162) and 
Wordwise ROM (*FX163) by Computer Con- 
cepts. The presence of the correct code at the 
second processor end of the Tube can be 
simply tested by checking that HIMEM has 
been changed.

Chaplin s listings 


LISTING 2 P 

This program (listing 2 on the yellow pages) 
should be run in the 6502 second processor 
under HiBasic. 

The machine code generated is automatical- 
ly saved, with the correct reload and execution 
addresses, as XJOTUBE in directory M. This 
code only operates with the code generated by 
the first program (M.X_HIBAS) and may be 
run as described above. Under no circum- 
stances should M.IOTUBF^ be *RUN more

it changes the OSBYTE vector.

GRAPHICS 


JOIN THE 
MANDELBROT SET 

You can create amazing graphics using the Mandelbrot set technique - when you enlarge 
a minute area of a shape, more and more detail will be revealed 

ft! 


E very so often an abstract mathemati- 
cal topic captures the imagination of 
programmers to such an extent that 
thousands of hours of computer time 
are expended exploring it. Familiar 
examples are the search for larger and larger 
prime numbers in the early days of computers, 
and in the 1970s the programming of the 
evolution of cellular automata in John Horton 
Conway’s game, Life. 

One such topic currently arousing lively 
interest in computing circles is an object 
known as the Mandelbrot set. 

The Mandelbrot set is an area in the two- 
dimensional plane defined by the behaviour of 
a simple function when repeatedly applied to 
points in the plane. 

The whole Mandelbrot set is shown as the 
black region in the plot of figure 1(a). The 


coloured bands around the Mandelbrot set 
represent the behaviour of points as they get 
close to the set. 

The great appeal of the Mandelbrot set lies 
in the complexity of its shape, which grows 
when minute parts of the region are enlarged 
and examined in greater detail. The figures in 
the two sequences of plots shown in figure 1(b) 
to (d) and figure 2(a) to (d) were obtained by 
exploring smaller regions of the Mandelbrot 
set. Each plot is an enlargement of the entire 
square area outlined in the previous plot of the 
same series. 

In figure 1(d) a speck to the upper-right of 
the main Mandelbrot set turns out to be a 
miniature version of the whole set. In figure 
2(d) a symmetrical whirlpool is revealed to 
have a tiny Mandelbrot set at its centre. 

I’ll describe the programs the BBC micro 


used to derive these plots. The Mandelbrot set 
is named after Benoit B Mandelbrot who has 
studied it as one example of a class of objects 
whose appearance remains fragmented or ir- 
regular at any magnification. Such objects are 
known as fractals, and other fractals have 
already been described in articles in Acorn User. 



Figure 1b. Detail from main picture la 


The mathematical interest in the Mandelbrot 
set is that complex and unpredictable behav- 
iour results from the repeated application of a 
relatively simple function; the erratic and 
turbulent behaviour exhibited by this type of 
process may prove useful in modelling turbu- 
lence in physics. 

Before looking at the function which gives 
rise to the Mandelbrot set, I’ll examine a 
simpler function that behaves in an analogous 
way in one dimension. 

A turbulent function 

The following equations define, for a given 
starting value u, how the next term in the series 
should be obtained: 
xo = 0 

X] = X — x*x + u 

The function is then repeatedly applied, or 
iterated, feeding the value of x back into the 
function to give a new value of x. 

The iteration can be expressed by a Basic 
function FNt(u) as follows: 



Figure 1. The Mandelbrot set (a) has infinite detail. If we zoom in on the small boxed area, the result is 1b, 
and so on . . . These pictures can be generated using the values from table 1 with listing 2

50 DEF FNt(u) 

60 N% = — l:x = 0 

70 REPEAT x = x - x*x + u:N% = N% + 1 
80 UNTIL N% = 255 OR ABS (x)> 100 
90 =N% 

The variable N% counts the number of itera- 
tions carried out for a given starting value of u. 
For some values of u the value of the function 
rapidly becomes very large; because of the x 2 
term it is clear that as soon as the size of the 
function ABS (x) exceeds some criterion value, 
say 100, it will continue to grow without 
stopping. In such cases we count the number 
of iterations before this happens, eg, u = 2.4 
takes seven iterations to exceed the criterion: 
2.4, -0.96, 0.5184, 2.6497, -1.9710, 
-3.4561, -13.0004, -179.6111 
and so FNt(2.4) = 7. 

However, there is a set of starting values of 
u for which repeated application of the func- 
tion never causes x to grow large. I’ll call this 
one-dimensional set the ‘T’ set. For example, 
the behaviour for u = 2.0 is: 2, 0, 2, 0, 2, 0, 2, 
. . . etc. 

The value of x cycles indefinitely. The 
behaviour of the function is followed for a 
convenient number of iterations, in this case 
255, and so FNt (2.0) = 255. If this number of 
iterations is completed without the value of x 
exceeding the criterion, starting point u is 
defined as lying within the ‘T’ set. 

The program TURB1 in listing 1 on the 
yellow pages plots the behaviour of this iterat- 
ed function FNt(u) over a given range of 
values of u. It prompts for two numbers - the 
starting value to be plotted, x, and the range 



Figure 1c. Zoom in from 1b 


over which the values should be examined, s. 
In other words, to plot the range u = 2 to u = 3 
the values x = 2 and s = 1 should be given. The 
program divides this range into 256 points and 
plots the value of FNt on the vertical axis for 
each of these points. 

The result of this plot is shown in figure 3. 
Values up to approximately u = 2.25 belong to 
the ‘T* set. Beyond u = 2.25 the behaviour of 
FNt(u) becomes highly erratic. The number of 
iterations needed for the function to exceed the

centre of the ‘whirlpool’. See table 1 for the values to generate these pictures from listing 2 


criterion value varies wildly from one point to 
another close to it. The fractal nature of this 
function will be seen if you try plotting smaller 
ranges of values within the region of turbu- 
lence; for example, between u = 2.3 and 
u = 2.300001. 

The Mandelbrot set 

The iteration just described defines a set of 
points in one dimension. In a similar way, the 
Mandelbrot set is a set of points in two 
dimensions defined by a function in x and y 
when iterated with a given starting value. 
Stable starting points which when iterated 
remain small, are said to belong to the 
Mandelbrot set. Starting points which cause 
the function to grow rapidly are said to lie 
outside the set. The function which causes this 
behaviour is most simply defined in terms of 
complex numbers. The following description 
avoids the need for an understanding of com- 



Figure Id. Note the miniature Mandelbrot set! 


plex numbers by giving the function in terms 
of ordinary arithmetic, as it would normally be 
expressed on a computer. 

The Mandelbrot function of a point (u,v) is 
simply defined by: 
xo = 0 

Yo = 0 

X] = x*x — y*y + u 
y] = 2*x*y 4- v 

This can be expressed in Basic as a function 
FNm (u,v) as follows: 

60 DEF FNm (u,v) 

70 N% = — l:x = 0:y = 0 
80 REPEAT y2 = y*y:x2 = x*x: 
y = 2*x*y + v:x = x2 - y2 + u:N% = N% + 1 
90 UNTIL N% = 255 OR x2 + y2 > = 4 
100 =N% 

This time we use the distance of the point (x,y) 
from the origin as a measure of the size of the 
function. It is easily shown that as soon as the 
distance of (x,y) from the origin exceeds 2, the 
size of the function will then continue to 
increase rapidly with successive iterations. The 
entire Mandelbrot set therefore lies inside the 
circle defined by: 
x 2 +y 2 = 4 

and we can disregard points outside this circle, 
coloured grey in figure 1(a). In FNm (u,v) we 
therefore iterate until: 
x*x + y*y > = 4 

Again, we follow a point for up to 25 itera- 
tions. This maximum number of iterations was 
chosen so that the numbers will fit into one 
byte when they are to be saved to disc in

MANDEL2. With a higher value the bound- 
ary of the Mandelbrot set is slightly sharper, at 
the expense of longer calculation times. 

Points for which FNm(u,v) = 255 belong to 
the Mandelbrot set, and are traditionally col- 
oured black. The equally fascinating behaviour 
of points outside the Mandelbrot set can be 
shown by using different colours to represent 
the number of iterations before FNm(u,v) 
exceeds the criterion. We have seven remain- 
ing colours to assign to the 254 different 
possible values of FNm(u,v). The way that 
these colours are assigned will be crucial in 
determining the amount of detail that can be 
seen in the area surrounding the set. 

There are two possible approaches to assign- 
ing these colours. The first is to calculate a 
fixed mapping of function values to colours.

Table 1 . The values needed to produce figures 1 and 2 

and then use this mapping for all pictures 
produced for different parts of the Mandelbrot 
set. The advantage of this is that in a series of 
enlargements, such as in figure 1, successive 
pictures maintain the same colours for the 
same features in the plots. Also, the display can 
be built up as the picture is calculated. 

The second approach is to calculate the 
value of the function FNm(u,v) for every point 
on a particular plot, and then on the basis of 
the values present in that plot assign the 
colours to give the desired detail. This ap- 
proach was used to give the second series of 
four plots in figure 2 and a program using this 
method is given towards the end of the article. 

Mandelbrot set program 

The program MANDFL1 (listing 2), uses the 
first approach of assigning colours to points 
not in the Mandelbrot set to give a series of 
coloured contours using a fixed mapping 
function. It plots the points as they are calculat- 
ed directly in eight colours within a square of 
resolution 128 x 128. Figure 4(a) to (d) shows a 
series of screenshots produced using the 
MANDEL1 listing. 

The original program used the Acornsoft 
Graphics Extension ROM to give an additional 
eight shades consisting of mixtures of 



Figure 3. Screen plot from listing 1 shows erratic fractal behaviour 


successive pairs of the eight standard colours. 
The version given here can be used to plot 
either with just eight colours, or with eight 
colours and eight shades using the GA'R (or on 
a Master 128). The version of PROCgcol in 
lines 620-640 should be used for an eight- 
colour plot, with maxcol% set to 7 in line 60; 
for 16 colours the version of PROCgcol on 
lines 660-710 should be used, with maxcol% 
set to 15 in line 60. The 16 colour version 
works by setting D% and E% to the values of 
adjacent logical colours for odd values of B%, 
and to the same logical colour for even values 
of B%. The VDll statement in line 690 then 
sets up a shading pattern, which the GCOL 
statement in line 700 selects for plotting. 

The program uses a rather unusual method 
of plotting the 128 x 128 points on the display 
so that a coarse lower-resolution view of the 
whole picture appears quite rapidly, enabling 
you to check that the desired part of the plot 
has been correctly chosen. Instead of plotting 
each of the pixels individually, starting at one 
corner and scanning the display, it ‘tiles’ the 
display, first with one 128 x 128 square, then 
with four 64 x 64 squares, then with 16 32 x 32 
squares, each time filling the square with the 
colour of the pixel in the lower left-hand 
corner (lines 560-590). The test on line 530 
ensures that each of the 128 x 128 values is 
actually only calculated once, so that the 
program takes just marginally longer than 
plotting individual pixels in strict sequence. 

The main program begins on line 60. It first 
sets up a text window (line 100), and then 
prompts for the bottom left-hand point of the 
square to be plotted, x and y co-ordinates, and 
the length of the side of the square s. The entire

Mandelbrot set fits in the square with origin 
(x,y) = (-2, — 1.25) and side s = 2.5. The 
plots in figures 1 and 2 were made with the 
values of x, y, and s shown in table 1 . 

For each point in the 128 x 128 area the 
program calls PROCpt which calculates the co- 
ordinates (x,y) of the next point to be plotted 
and calls FNm for that point. The value 
returned is then mapped to one of the screen 
colours by the array C%(1) . . . C%(255) 
whose elements are set to the values 0 to 
maxcol% to determine the mapping of func- 
tion values to colours. PROCgcol is called to 
choose that colour for subsequent plotting, 
and a square is plotted at the screen co- 
ordinates X%,Y%. 

The mapping function, found after much 
experimentation, is logarithmic and is given in 
lines 130 to 160. The VDU statements in lines 
170-220 reassign the physical colours to logical 
colours 0 to 7 to give a pleasing sequence of 
colours. The resulting assignment of contour 
levels to colours is given in table 2, for the 
eight-colour version. 

Altering the contours 

The assignment of colours to the 255 contour 
levels is a crucial process in achieving a good 
Mandelbrot plot; if too many levels are as- 
signed the same colour, detail will be lost in the 
final plot. Conversely, if too many colour 
changes occur where the contour levels are 
changing rapidly, the display will be a blur of 
colour. The most flexible approach to plotting 
the Mandelbrot set and its associated contours 
is to save all the calculated points to a disc file; 
the assignment of the 255 contour levels to the 
more limited colours on the display can then be 
handled fairly quickly just by reading the 
points from the file. 

The program MANDFL2 (listing 3) creates 


82 


ACORN USER MAY 1986 



GRAPHICS 



such a 4k disc file of data; this time, the points 
are simply calculated in sequence and saved to 
the file without displaying them. As a measure 
of the program’s progress, the column number 
J% is printed out for each of the 128 columns. 

Plot data file 

The program MANDEL3 (listing 4), reads the 
data file created by MANDEL2, processes the 
points, and displays the resulting plot. MAN- 
DEL3 first reads in the function values and 
counts the number of points for each value 0 to 
255 in the array C%. It then assigns values to 
C% such that all function values with a value 
of 255 are plotted black, and the remaining 15 
colours are each assigned to approximately 
equal numbers of points (lines 200-270). Final- 
ly in line 390 the random-access pointer is reset 
to the beginning of the file, and lines 400-490 
plot the entire graphics display. 

Again, two versions of PROCgcol are pro- 
vided, and the appropriate version should be 
used depending on whether the GA'R is avail- 
able, with maxcol% changed to 15 in line 60 as 
necessary. Because of the large number of 
calculations needed for each plot, MAN DELI 
and MANDEL2 can take between two and 
four hours to run to completion, depending on 
the range of values being explored. It is 
advisable to save a screen-dump of every 
successful plot for future reference, using for 
example *SAVE PX FFFF3000 + 5000 typed 
in once the program has finished. 

There are countless fascinating shapes wait- 
ing to be discovered in the vicinity of the 
Mandelbrot set; in fact, the infinite detail there 


makes it certain that there are patterns which 
will go undiscovered forever. Readers finding 
particularly interesting regions in the set are 
encouraged to send them in to Acorn User, as 
screen dumps on disc. A review of the best 
plots will be featured in a future issue for the 
benefit of other explorers.

+ VAT 


ROM MANUAL

TUTOR CASSETTE 


Since its launch this has become by far the most 
popular word processor for the BBC Micro, 
with nearly 60,000 now in use worldwide. 

The main reason for this success is its 
simplicity. The more complex operations are 
menu driven, so there are no command names 
to remember. As a result even those unfamiliar 
with this software can use these features. In 
addition WORDWISE operates in a smooth and 
logical manner thus avoiding strange and 
unpredictable key sequences. 

This is a complete word processor giving 
the user total control over text entered into the 
computer. Simple block move and copy facilities 
allow any section of the text to be moved to 
any other part of a document - fast and 
efficiently. This marked section of text may also 
be printed or saved for future use. 

Embedded commands can be put into the 
text to control the overall page layout. These 
alter such things as the line and page lengths. 


centering, margins, automatic page numbering 
and heading and footing lines etc. Embedded 
commands are only necessary if the user wants 
to change the layout from the default. 

WORDWISE works with all filing systems 
such as disc, cassette and the new ADFS. It 
works with any printer that is compatible with 
the BBC Micro (most are) and is able to control 
all the special features of the printer such as 
underlining, italics etc. 

This latest version of WORDWISE has now 
been improved to include some of the 
WORDWISE PLUS enhancements such as faster 
loading/saving and protection against the 
overwriting of existing files. A variety of new 
embedded commands now make files totally 
compatible with WORDWISE PLUS. It works 
with a wide range of machines and extension 
shadow RAM systems, such as ARIES or 
WATFORD boards. 




PRINTERS 


DIY DUMPING 

Our printer expert provides a way for you to transfer user-defined characters to a 
printer automatically, and a printer dump program for character screens 


A hint referring to the automatic trans- 
fer of user-defined characters on the 
printer (Nov ’85, page 49) provided 
the motivation for coming up with a 
mechanism by which this can be 
done, and you’ll find three programs on the 
yellow pages using the technique. The last of 
these is a printer dump program for character 
screens which is similar to the machine-code 
version of the Acorn User UserDump ROM. 
These listings will work on Epson and Epson- 
compatible printers with double density graph- 
ics facilities such as the Citizen 120d, Star, 
Kaga Taxan, etc. 

The function *CDUMP (character dump) 
on the UserDump ROM decodes the screen 
version of the characters, whether user defined 
or not, and produces a perfect printed image, 
independent of mode. Figure 1 shows an 
example. Listing 4 gives a sample screen using 
user-defined characters. It contains the proce- 
dure ‘PROCreadparameters’ which is also used 
in the dumping program to determine the 
current mode and set up the line-length and 
number of lines per page. This enables the 
program to run in any mode - though user- 
defined characters have no effect in mode 7. 

The method of dealing with the characters 
depends on covering the eight ‘horizontal’ 
bytes per character of the Beeb’s user-defined 
characters to eight ‘vertical’ bytes for the

only minor modifications in listing 2 (added 
routines to read the character at the text cursor 
and to print the characters after translation). 

The programs all place the ASCII value of 
the current character into a byte reserved for 
the purpose - ‘char’. The routine (assembled at

‘code’) first reads the character definition of 
this character by an OSWORD call, into eight 
bytes reserved for it, starting at ‘cchar\ These 
are processed by ‘htov’ into eight bytes for the 
printer, starting at ‘pchar’. 

The processing method depends on the fact 
that ‘shift’ and rotate’ operations exist on the 
6502 which shift bytes either left or right. In all 
cases the bit shifted out is transferred to the 
carry bit. In the rotate instructions the previ- 
ous contents of the carry bit are shifted in, 
while in the shifts, a zero is shifted in. Thus the 
carry bit can be used as a temporary home for a 
bit which is then transferred elsewhere. There 
are 16 possible ways of dealing with bit 
transfers, illustrated in figure 2. The particular 
combination used in this transfer is: 

LSR byte 1 

ROR byte 2 

This shifts the least significant bit of byte 1 into 
the most significant bit of byte 2. Byte 1 has 
zeros shifted in to the right-hand end, and the 
bits shifted out of byte 2 go to the carry, but 
are ‘lost’ in subsequent operations (figure 3). 

The graphics/text program HTOV (listing 
5) illustrates how the bit-by-bit conversion is 
carried out - it is an animated ‘visual aid’ 
which might be helpful to teachers in other 
contexts. The variable delay at line 160 gives a 
10 second delay between moves. This can be 
altered, or individual moves caused, by using 
the space bar. Figures 4, 5 and 6 illustrate a set 
of character bytes and printer bytes before, 
during and after conversion. They are print- 
outs from the HTOV program. 

In listing 1, CHARPRT, single characters 
are prompted from the screen, either as their 
ASCII values or as characters, and their de- 
fined representations are printed. Figure 7 is a 
sample output from the program. 

In TYPWRTR, listing 2, the printer repro- 
duces exactly any text which is typed at the 
keyboard, using any character definitions you 
have altered. You can define Greek characters 
and type them in directly. If French accents are 
required, define them and type them in. You 
enter your text a line at a time, and it is shown 
on the screen (figure 8). The cursor ‘sticks’ at 
the end of the line, and beeps, just as it would 
on a typewriter. At the conclusion of editing 
the line (the Copy and Delete keys can be used 
as normal), pressing Return causes the line to 
be printed. The program runs in mode 3 giving 
an 80 character line length. 

Note that the program allows all characters 
to be redefined, using *FX20,6, and so must 
run at &600 above the normal value of PAGE. 
If the value of PAGP^ seems too low for the 
current filing system the program is halted. 
You can change this by checking lines 240 to 
290. If you have discs and the normal DFS

Figure 7. Sample output of listing 1, the CHARPRT program 


THIS PR06MM /LLOMS YOUR BEEB ♦ PRINTER TO /4CT /IS A TYPEWRITER. 

You can redefine characters (notice the A has been altered), and type in a line 
at a tine. They are printed uhen you press return. 

If you redefine the characters correctly you can type in foreign characters . 

I have redefined sone of the nore obscure ones to use as French characters. 

Et naintenant je peux 6crire en Fran9ais!! 
foret, sGr, hate, tot, *, frtre. 

Figure 8. The TYPWRTR program, listing 2, reproduces text with any character definitions you have altered 


chips, when the default value of PAGE is 
& 1 900, then simply prefix the program by: 

1 IF PAGE <&1F00 THEN PAGE = 

& 1 F00:CHAIN“TYPWRTR” 

Your desired character definitions can be 
carried out either externally by another 
program, or internally by altering 
PROCdefinechars (which currently only rede- 
fines A of the printing characters). 1 wanted to 
use another utility (DEFCHAR) to define the 
characters. To do this you must remove the 
*FX20,6 call, as this destroys any previously 
defined characters in the normal range. 

Listing 3, CDUMP, is a procedure for 
merging with another program (for example 
the SPLSCRN program). It may then be 
activated by inserting: 

PROCcdump 

where you want the dump to occur. You’ll find 
instructions for carrying out program merging 
in the user guide. 

CDUMP will work in any mode, but will not 
print any dots produced by graphics com- 
mands or any characters printed at the graphics 
cursor. PROCrcadparameters is used to read 
information for the printer, as well as charac- 
ters per line and lines per page. These para- 
meters are used to control the printing of the 
prepared bytes in PROCdump. 

PROCdump (lines 10480 to 10650) is ex- 
plained line-by-line below: 

10490 Restore default screen and enable 
printer 

10500 Set linefeed on printer 

10510 Loop for vertical scan 

10520 Set up printer to print correct num- 
ber of dots 

10530 Read character at text cursor 
(A% = 135, line 10770) 

10540 Loop for horizontal scan 
10550 Switch dots round 
10560 Loop to print eight bytes 

10570 Print one byte 

10580 Double up if mode 2 or 5 
10590 NEXT 1% 

10600 Disable printer, advance text cursor 

and enable printer 
10610 NEXT X% 

10620 Linefeed 
10630 NEXT Y% 

10640 Formfeed, reset printer and disable 
printer 

The conversion of CDUMP to a full machine 
code program to dump the graphics screen is 
largely a matter of doing arithmetic in assem- 
bly language and adding a print routine. This is 
relatively simple if you are into that sort of 
thing. If not, buy the very reasonably priced 
User Dump ROM!

QUESTIONS FOR 
THE BOARD 

Choosing an expansion board to extend the capacity of your BBC micro or Electron is not easy. 
Here we answer your most common questions and summarise what the options are 


Chris Drage 


T he BBC micro was not designed to 
accommodate extra boards despite be- 
ing able to cope with 16 paged ROMs. 
Physically a 12-socket board takes up a 
great deal of space inside the machine, 
and any board covering the Beeb’s RAM area 
is inviting overheating problems with the 
resulting corruption of memory. Picking up 
the lines necessary for operation can provide 
some soldering headaches, although many 
boards are now of a plug-in-and-go design. 
Perhaps the main factors to consider when 
choosing a ROM expansion board are: 

Ease of installation 
Reliability in operation 
Physical stability of the board 
Offers sideways RAM 
Compatibility with future expansion plans 
The reviews which appeared in the April 
and September 1985 issues deal with most of 
these points. 

Options 

For the maximum number of ROMs, the 
Exprom, ATPL and Watford SSRB boards 
provide for 16 paged ROMs. 1 have extensive- 
ly used both the ATPE and the Exprom boards 
and found them easy to install and reliable. 
Another system worth considering is the Com- 
puter Village CVX16-2, but this one’s awk- 
ward to fit. If you wish to use sideways RAM 
to the full, then the Ramamp RA32 board 
scores well. Utilising 32k of dynamic RAM it 
represents a cost-effective means of combining 
sideways RAM and ROM expansions, but the 
number of ROM slots available is limited to 10. 
The Aries B12 is another well-constructed 
board. Its ease of installation and reliability, 
combined with the fact that it may be used with 
the Aries B32 shadow' RAM board, makes it an 
attractive option. 

Several manufacturers have opted for exter- 
nally mounted boards. Perhaps the most cost- 
effective and simple ROM expansion system is 


the excellent ROM-cartridge system from 
Viglen Computers (reviewed in AU October 
1984), which enables you to utilise an unlimit- 
ed number of ROMs safely, although if you 
have 30 ROMs it might be more expensive 
than a ROM board. I do not recommend the 
use of externally mounted ZIF sockets as the 
risk to valuable ROMs is too great. Other 
larger, external boards are produced by GCC 
(Cambridge) and HCR Electronic Services. If 
you want the best of external ROM sideways 
RAM expansion then both these systems are 
sure to please. Provided you have additional 
driver boards installed, each has the added 
bonus of being portable. The Micro Pulse 
Rombox is an elegant but expensive way to 
expand one ROM socket. With the purchase of 
additional leads, this system is also portable. 

All the ROM expansion options above 
provide various solutions to the BBC micro’s 
lack of ROM sockets. You will have to judge 
for yourself whether you are likely to make 
sufficient use of the facilities each offers to 
justify the cost. 

The system for you 

Many people expand the sideways RAM po- 
tential of their computers in preference to 
obtaining extra ROMs, and again we are spoilt 
for choice. I’ll offer a few pointers and include 


the summary and score tables carried in De- 
cember. Any changes to the figures are the 
result of hardware improvements, updated 
software (in Solidisk’s case), and price changes. 
In addition, I’ve included several questions 
which are typical of those Acorn User receives 
on the subject of sideways RAM. 

Q I am a novice. I simply want to add 16k of 
sideways RAM to my machine. 

A Of the boards reviewed the Ramamp RA16 
offers reliability and the best value for money. 
Easy to fit, but more expensive, is Acorn User's 
own UserRAM. 

Q What is battery backup? 

A Many ROM boards provide a facility for 
you to add a small Ni-Cad battery at a later 
date. This is charged by the computer and 
provides a means for sideways RAM to main- 
tain its current ROM image w'hile the comput- 
er is switched off. This is particularly useful for 
those who arc developing their own sideways 
software. The reviews in the April and Sep- 
tember 1985 issues refer to the boards which 
provide battery backup. 

Q What is write protection? 

A Several RAM boards provide the facility of a 
write protect switch (or allow you to add one). 
Once invoked, the switch prevents any writing 
to sideways RAM by the user or by the ROM 
image.

Summary of what the eipansion boards have to offer, how much they cost and where to get them 



COMPATIBILITY 


Q Can I run any program in sideways RAM? 

A No. Generally speaking only machine code 
programs written to load at &8000 to &BFFF 
can run from sideways RAM unless you wish 
to store programs in ROM filing system 
format. Looking at your disc contents (using 
*INFO.*.*), sideways ROM images normally 
appear as either: 

progname 008000 008000 004000 (16k) 
or progname 008000 008000 002000 (8k) 

Q Can I use the ROM Filing System? 

A Yes, you can. One of the best packages 1 
know of that enables you to convert your 
favourite software to run from sideways RAM 
is Beebugsoft’s Romit. This package creates a 
ROM image of the program from which you 
can blow an EPROM. It works by 
downloading the program to its correct execu- 
tion address in the main RAM and running it. 
Also, the disc supplied with UserRAM con- 
tains a ROM tiling system formatter which will 
take standard Basic program files and format 
them, enabling them to be loaded into side- 
ways RAM and subsequently loaded as re- 
quired. A similar program can also be found in 
Bruce Smith’s The BBC Micro ROM Book 
(published by Collins at £9.95). 

Q Please tell me, how do you load software 
into sideways RAM? 

A Most RAM board manufacturers provide 
information about how to do this. Typically 
the command: *L()AD ROMimage 8000 
< RETURN > followed by either CALL! — 4 
(or pressing Break), will initialise a ROM 
image. The B -F 128 and Master use a unique 
command : *SRLOAD ROMimage 8000 W Q. 
Several suppliers such as Solidisk, Ramamp 
and HCR provide elegant menu programs to 
do this automatically for you. 

Q I am an experienced programmer who wish- 
es to develop my own ROM-based software in 
sideways RAM. 

A The Acorn User UserRAM module has a 
very substantial range of software to support it 
and would be an ideal tool for this purpose. 

Q I want to utilise 32k of sideways RAM so I 
can load two ROM images. 


A The HCR Electronics 32k board is a reliable 
and well-designed board. The Solidisk 32k 
board can also be recommended if you are 
competent with a soldering iron. 

Q I am in charge of a network of BBC micros 
in an educational institution. Should I pur- 
chase RAM expansion boards for each net- 
work station? 

A Using sideways RAM is a cost-effective 
means of distributing ROM-based software. 
UserRAM, Ramamp RA16 and HCR 16/32k 
units can all be recommended. Most software 
publishers are now prepared to grant software 
licences for network users. 

Q 1 have an ATPL Sidewise ROM board and 
want to add another 16k of sideways RAM to 
that already present. 

A The only system I know that offers such 
expansion is the RAM module produced by 
C F Terrell, 7B Essex Gardens, Hornchurch, 
Essex RM1 1 3EH. Tel: (04024) 71426. Alter- 
natively, the Aries B32 is now compatible with 
the Sidewise board. 

Q I am a hobbyist who wants to use sideways 
RAM to the full. 

A The Solidisk 64k system is probably the 
most versatile unit available at present. The 
new, updated software allows you to configure 
the RAM in a number of useful ways. You 
must be prepared for some headaches should 
you install it yourself, though! 

Q 1 own an Electron. Can I upgrade it with any 
sideways RAM board? 

A The only system available at the moment is 
the Advanced Computer Products RAM ex- 
pansion system at £29.90 from 6 Ava House, 
High Street, Chobham GU24 8LZ. The 
Solidisk EFS disc interface is also supplied 
with 16k of sideways RAM. Both systems 
require a Plus 1 to be fitted to the Electron. 

Q I want to upgrade my BBC model B to 
include shadow RAM, sideways RAM and 
sideways ROM expansions. Which units 
should I choose? 

A For reasons of compatibility it is best to stick 
with one manufacturer’s product. In this case 
the best solution would be to install the Aries 


B32, B12 and two 6264 CMOS RAM chips. 
Look out for reviews of the new 256k RAM 
expansion system from Solidisk, which may 
also provide the answer. 

Q 1 own a Viglen Cartridge ROM system. Is 
there any value to be gained in installing a 
sideways RAM board? 

A Sideways RAM can be configured into DFS 
workspace or a printer buffer, both of which 
are advantageous. The Ramamp RA16 and 
Solidisk systems offer software to achieve this. 
Q I have heard that sideways RAM can be 
configured into a ‘silicon disc’. W'hat is this and 
how useful is it? 

A The Solidisk 64k and 128k boards can be 
configured into a silicon disc. The computer 
thinks that another disc drive has been fitted, 
thus DFS commands will work with the 
sidew r ays RAM. The RAM-disc is volatile, so if 
you turn the computer off the RAM-disc is 
lost. It is useful for spelling checking and 
database work as the speed of access is about 10 
times faster than any conventional disc drive. 

Q I use a Solidisk 32k sideways RAM system 
but I want to expand my Beeb’s ROM capacity. 
Can I do this without compatibility problems? 
A There is only one reliable way that I know, 
and that is to add a Ramamp ROM16S card. 
This will give you an extra six ROM slots with 
the 32k and 64k boards. 

Q Is UserRAM compatible with any of the 
popular sideways ROM expansion boards? 

A The only boards I have actually had 
UserRAM running properly with are the Wat- 
ford MKII board and the HCR internal board. 
Maybe readers have found other combinations 
I have not been able to test yet. 

The final answer prompts me to request 
readers to help us assemble a table of RAM / 
ROM compatible expansion boards. The only 
true test of compatibility of specific products is 
reliability in general - everyday use over a long 
period of time. If you have used any ROM 
board/RAM board combinations successfully 
we would love to hear from you.

ROMS 


COMPATIBILITY 

QUEST 

Join Acorn User’s quest to find which ROMs work with what, and to persuade software 
houses to leap into action to solve those Incompatibility problems 


Simon Williams 


W ith only 16 slots available for 
expansion ROMs, and many 
times that number of products 
vying for attention, it makes 
sense to choose wisely, by 
studying advertisements and reading reviews 
in magazines such as Acorn User. Even then, 
though, you’re guaranteed little, due to an 
exasperating and increasingly prevalent prob- 
lem which rarely seems to get a proper airing. 

The more sideways ROMs you buy, the 
more conflicts appear between different prod- 
ucts. These ‘tiffs’ vary from one ROM answer- 
ing another’s command, to two ROMs refus- 
ing to live in the same machine together. There 
are various ways round these little battles, but 
none of them make life any easier for the 
average micro user. 


Avoiding conflict 

You can buy an extension zero insertion force 
(ZIF) socket and only plug in the ROM you 
want at any time. This can be awkward, 
however, if you need to call more than one 
ROM during a session. An alternative is a 
couple of sideways RAM units, into which you 
can load disc images of your own ROMs, but 
this removes the convenience of having ‘in- 
stant’ ROM software in the first place. 

Another possibility is the ‘ROM manager’ 
ROM, which will ‘knock out’ other ROMs on 
request. Some routines even survive a hard 
reset and the chips can then only be reawoken 
with a specific command. 

It still doesn’t solve the problem of working 
out which ROM caused the conflict in the first 
place, however. 

So why not find out from the software 
publisher before buying his product? Mainly 
because the standard reply is ‘It’s impossible to 
test our new product with every piece of 
software on the market’. Fair enough, but they 
should at least try some of the more obvious 


combinations. I recently had a new ROM 
which made Wordwise Plus , normally a very 
mild-mannered chip, include random disc cata- 
logues in new text files! How about the disc 
utility chip which so disliked Disc Doctor that it 
turned it off each time the micro was reset! Or 
the trio of chips XROM, YROM and ZROM 
which require an impossible order of prece- 
dence, eg: 

XROM > YROM AND ZROM 
YROM > ZROM 
ZROM > XROM 

Not only are ROM conflicts annoying, but are 
often extremely hard to trace. Intermittent 
‘scuffles’ may only break out when using 
obscure sections of code, and the conditions 
are then very' difficult and time-consuming to 
reproduce. Gradually removing chips from an 
expansion board until you hit on the offending 
component may be some people’s idea of fun 
but I’ve far better things to do with my 
computing time. 

So what’s to be done? Well, for a start, 
software companies could be encouraged to 
stick to the rules laid down by Acorn. Many of 
the conflicts between ROMs are brought about 
because the code is not written using Acorn’s 
service routines. 

For instance, ROMs which access the screen 
directly are asking for trouble. Then there are 
ROMs which need workspace (normally ‘lan- 
guage’ ROMs) and aren’t choosy about where 
they find it. However clever a program is, it 
will not gain popular acceptance if it sits there 
in the micro giving no quarter to any other 
program in the machine. 

But it isn’t all down to the software compa- 
nies. There are things users can do to help 
reduce the problems, and the most obvious of 
these is to help compile a list of troublesome 
ROMs. Once the software companies know 
that a particular ROM isn’t happy with others, 
the onus is on them to sort out the problem. 


You can help 

What we’re proposing is a chart of conflicting 
ROM software. Write in and report any ROMs 
you’re having trouble with - send your com- 
ments to: Simon Williams, ROM Compatibil- 
ity, Acorn User , 141-143 Drury Lane, London 
WC2B 5TF. This doesn’t mean having a dig at 
a product which doesn’t do what you imagined 
it would, but rather providing details of 
clashes you’ve come across in your machine. It 
takes two to conflict so you should have 
isolated the offenders before writing to us. 
What we’ll need to compile a list is: 

• Basic specification of your machine: make, 
type and version of any DFS. 

• Make, version and amount of any extra 
memory (shadow or sideways). 

• Make and type of any second processor. 

• Make and type of any peripherals attached 
when the conflict occurs. 

• Make and version of any other ROMs in 
your machine (other than those below). 

• Make and version of the two ROMs you 
think are causing the conflict. 

• Nature of the conflict (eg, machine crashes 
with a row of asterisks in the middle of the 
screen). Is there an initial letter you can use to 
avoid conflict? 

• Response of the software company, if 
you’ve reported the trouble (eg, ‘We’re work- 
ing on it’ or ‘It’s fixed in version 7.23’). 

• Any fix you’ve discovered to resolve the 
conflict in question. 

The more help you can give us in reporting 
troubles you’ve had with conflicting software, 
the sooner we can help other users and the 
software companies to reduce the problem. 

To kick off our compatibility quest we re presenting a list of 
ROMs and what Acorn micro’s they’re compatible with on 
the ye! low pages. You'll also find an embryonic chart of 
conflicting ROMs - we want you to supply more details - 
and a table of prefix characters used by ROMs see yellow 
pages 119 to 120

COMPETITION 

ENTER THE GREAT PI RACE 

We challenge you to calculate pi the fastest - and win one of three Kaga Taxan KP810 printers 


The idea of this month’s competition is quite 
simple (in theory at least!). What we want you 
to do is to calculate the value of that great 
constant pi! Of course, its value has yet to be 
set definitely as it is one of those numbers that 
goes on and on . . . to as many decimal places 
as you care to choose. What we want you to do 
is calculate the value rounded up to 500 
decimal places accurately, and print out the 
value of each place on the screen as it is 
calculated, in the shortest possible time. 

The idea came from Peter Corlett. He and 
James Tout had written a program in assem- 
bler that calculated pi to 500 decimal places in 
less than a minute. The rules are: 

• Your program must use one of the 
recognised standard series (see box) for calcu- 
lating the correct value of pi rounded up to 500 
decimal places as given in figure 1 . 

• All calculations must be done within the 
program. No values can be read in. Entries 
which simply divide one number by another 
will not be allowed. 

• Each place must be displayed on the screen 
as it is calculated. 

• The time taken must be displayed on the 
screen when the program has finished. 

• All programs must be written in mode 6. 

• No DATA statements are allowed. 

• The programs must be written legally, so 
no poking the screen or using routines in the 
Basic or MOS, other than those documented 
by Acorn, ie, OS calls. 

• Programs cannot use sideways RAM or 
shadow memory on any machine. 

• The program must be your own work and

coloured fill patterns and 24 tone patterns, and 
to mix foreground and background colours. 

Harry Sinclair’s Sprite designer from the

figures quickly, then edit, clone or mirror them 
and move them around the screen.

provides 23 new black 
and white shades; 
♦EXPAND - returns a previously *COM-

lists the sideways ROMs present in your 
machine; ♦ SCREEN - saves the current graph- 
ics screen to disc or tape; ♦SCROLL - moves a 
scrolling message across the mode 7 screen; 
and ♦VARS - lists all names used for non- 
integer variables. 

A 22-page manual is included, which ex- 
plains in clear simple terms how to get the 
most from your UserROM , and includes many

Entering listings 

Where possible , programs are listed with line numbers in increments of 10 so 
type AUTO < RETURN > for automatic line numbering before you start. 
Don’t type a space after the line number. To list your program so it appears 
identical to the printed version in the magazine, type: 

LISTO 1< RETURN > WIDTH 40 <RETURN> LIST < RETURN > 
With screen modes 1,4,6 or 7, WIDTH 40 is not needed. Occasionally, for 
clarity, programs are listed with a text width different to 40 characters. 


Typing errors in Basic will usually cause error messages when the program 
is run. Finding errors in assembly language listings can be harder so we 
provide small , checking routines (called ' checksums' ) where possible. 

All the Yellow Pages listings will work with Basic I, 2 and 4 (unless stated 
otherwise) and with operating system OSl.2 or later operating systems. 

Great care is taken to ensure the listings printed are correct but turn to 
Blunder box (page 17) to check if any errors were made in the previous issue.

UTILITIES 


How to enter It’s Quicker by Tube 

Martin Chaplin presents three listings in this month's yellow 
pages . Listings 1 and 2 assemble two machine code routines; 
one to sit in the second processor and the other to live in the in - 
putjoutput processor on the main board . Listing 3 tests the 
extended facilities provided by listings t and 2 . 

Listing 1 assembles the code intended for the second 
processor. Make sure that you are using HiBasic when running 
this listing. Because listing l contains a lot of assembly 
language a checksum routine has been included (lines 2350 to 
2370). Any errors found will be reported with a message 
prompting you to check your listing. The assembled code is 

saved at line 2380 with the filename M.X HIBAS . 

If you have made a typing error while entering listing 1 then 
ensure that after you have corrected your mistakes you save 
the new version. Before running listing / again you should 
press the Break key and either type OLD < Return > or load 
the corrected version back in. 

Listing 2 assembles the machine code routine which lives in 
the main BBC micro. It can be run using Basic 2 or HiBasic. 
Again , a checksum routine has been included (lines 1460 to 
IJOO) to detect any typing errors made. The finished code is 
saved with the filename M.IOTUBE at line IJIO. 

To implement the enhanced version of HiBasic , the follow- 
ing steps should be taken: 

/. Reset machine by pressing CTRL-Break. 

2. Load HiBasic if it is not resident in the machine. 

3. Check that HiBasic is operating correctly by typing: 
PRINT ~ HIMEM 

The value printed should be 8cB800. 

4. Set up the BBC micro end by typing: 

*RUN M.IOTUBE 

3. Set up the second processor end by typing: 

*RUN M.X HIBAS 

The extended facilities are now available for use. You can 
now enter listing 3 to test the extended HiBasic. Note , though , 
that listing 3 makes use of the new keyword ' TUBE ' and so 
must only be entered once extended HiBasic has been in- 
stalled. Running listing 3 will take you through a demonstra- 
tion of the new commands. 

Points to watch 

Net or ADFS users should note that directories ' A' and ' M ' 
are used and these should be created using *CDIR beforehand 
to avoid a ' not found ’ error. 

The code M.IOTUBE should not be *RUN more than once 
without pressing the Break key, since it intercepts the 
OSBYTE vector.

How to enter DIY Dumping 

All five programs are straightforward. As the assembler in each is short a 
checksum has not been included. With the exception of the ' HtoV’ listing all 
programs require an Epson or Epson compatible dot-matrix printer to work. 
Electron owners will obviously need to have the Plus 1 attached to be able to 
use a printer. 

The CDUMP program is numbered from line 10000 onwards. This is 
deliberate as it is not a stand alone program but instead a procedure that can 
be spooled onto the end of a main program. After entering CDUMP save it as 
an ASCII spool file thus: 

*SPOOL CDUMP 

LIST 

*SPOOL 

The program will list to tape or disc. 

The program ‘ SPLSCRN ' tests CDUMP. Enter and save SPLSCRN. 
CDUMP can be appended to the end of SPLSCRN by performing, 

* EXEC CDUMP. 

To use CDUMP you will need to insert an extra line at the point where you 
wish the character dump to take place. In the case of SPLSCRN place it as follows: 
7 / PROCcdump

Checksums 

David Johnson-Davies listings / and 2 (Mandel I and 2) provides this month’s 
checksums. Numerous variables are used in the programs so it is possible that 
you could enter one of these incorrectly thus inhibiting the program’s action. If 
you cannot trace the error ’manually’ then use the checksum. You will need the 


BSUM program provided in First Byte of August 198 J or use the *CHECK 


command present on 

the Acorn User User ROM (see page 102).

Electron Keys 

Entering Basic programs on the Electron can be a much quicker process 
because of its single key entry facility. By pressing a combination of keys a cor- 
responding Basic keyword is entered onto the screen and into your program. 
This program by Alan Crabb allows Beeb users to emulate this useful Electron 
facility. 

There are 29 keywords in all and the keywords on the keys are exactly the 
same as for the Electron, so anyone using both the BBC and the Eletron can 
still use the single keyword entry on the BBC. 

With the utility installed using the single entry is simple. Ensure that caps 
lock is engaged (the caps lock light should be illuminated), press CTRL and 
the key on which relates to the keyword needed. To get the usual CTRL effect 
simply disengage caps lock and the keys have their normal effect (ie, CTRL - 
U deletes present line). 

The routine may be turned off using *CODE 0 0 and re-engaged using 
*CODE 0 l. To get rid of it permanently type *FX 247 < Return > then press 
Break. A list of the keys and the keywords they produce is given in figure l. 

The routine works by intercepting the Operating System ReaD CHaracter 
routine (OSRDCH). It decodes the value for the character read and if caps 
lock is engaged, CTRL pressed and the key legitimate, the routine inserts the 
keyword and Return if OLD or RUN into the keyword buffer. The routine in- 
tercepts Break using *FX 247 and re-initialises itself. 

How to enter Electron Keys 

The program can be entered in the normal way. Save the source program 
before attempting to run it. Correct any errors that may occur. Take care to 
enter the keyword data exactly as shown, and all on a single line. The 
program incorporates a checksum routine that will check that your machine 
code is correct. All being well you will see the message 1 Electron Keys’ 
displayed. 

The program assembles from &900 and also requires space in page &.A. 
This area is normally used by the cassette filing system, serial port and sound 
buffers. If you need to use any of these facilities the machine code will need to 
be assembled elsewhere. In such cases the checksum will be incorrect.

The Great Acorn User ROM 
Compatibility Quest has begun 
(see page 96)! Here is the start of 
a ROM compatibility chart 
that we want you, the reader, to 
fill in. Let us know of any clash- 
es, no matter how small, that you 
have encountered. Also, if you 
know that a certain ROM is 
incompatible with another then 
we want to know. Everyone who 
supplies some information we 
can use will get a name check in 
Acorn User. 

In addition we want to hear 
about any prefix characters used 
by a ROM so that we can build 
up a table. In addition we're 
interested in any *FX calls used 
by any ROM, other than those 
described by Acorn. 

Simon Williams will be co- 
ordinating your details so send 
them to him care of the A U office 
and mark your letter ‘ ROM 
Compatibility '. 

This month we're carrying two 
charts. The first (left) deals with 
machine compatibility and lists 
which ROMs will work with 
which of the Acorn micros, fol- 
lowed by details of any ROM 
incompatibilities we know of. In 
some instances a fix' is provid- 
ed! Finally, chart two (page 120) 
lists letters that commands may 
be prefixed with to ensure that a 
particular command reaches the 
ROM in question . 

We propose that ROM com- 
mands should be prefixed with 
the company's intials. In future 
all AU firmware will allow the 
use of *AU as a prefix. This 
avoids use of one prefix charac- 
ter by several suppliers. 

So help us to help you - we 
look forward to hearing from 
you!

liams, ROM Compatibility, c/o

GAMES 



BARRELS OF 


FUN ON TAP 



‘Tapper’, US Gold, BBC B, £9.95 (cassette 
or disc) 

This arcade game is a barrel of laughs. Several 
barrels, in fact, because you play a frantic 
bartender whose job is to keep an ever- 
growing crowd of customers satisfied. They 
sidle into various parts of the bar and you have 
to leap around, filling glasses from the beer 
taps, slinging them along the bar, saloon-style, 
and collecting the empties they sling back at 
you. You lose a life if you keep a thirsty 
customer waiting too long. 

(Actually, the instructions have been care- 
fully edited for the benefit of under-age users, 
and would like us to believe that it’s really a 
soda fountain and you’re only serving fizzy 
pop. But that doesn’t fool anyone.) 

As you become proficient, you’ll be promot- 
ed from the Wild West Saloon to the Jock Bar 
(patronised not by thirsty Scotsmen, thank 
goodness, but by sporty people in baseball 
caps), then to the Punk Bar, with its purple- 
haired customers, and finally to the Space Bar, 
full of creatures almost as weird as the punks. 
In between bars, you can pick up bonus points 
in an interlude with the ‘Soda Bandit’. He 
shakes up cans of Budweiser - sorry, soda pop 
- then shuffles them around rapidly. You score 
by picking the one he hasn’t shaken and 
opening it. If you guess wrong, you’re 
sprayed. Either way, you’re soon back in the 
bar with a hoard of impatient customers. 

Sometimes, one of the customers is kind 
enough to leave you a tip. 

If you can collect it without mishap, a pair of 
dancing girls start doing a can-can and most of 


the punters stop drinking to watch - which 
gives you a breather. It’s all good fun and very 
reminiscent of The Sun, the Acorn User local. 

The instruction leaflet was obviously print- 
ed for an earlier version of the game, for 
another micro. 

It suggests, for example, you can use a 
joystick on the BBC micro version, which you 
can’t (although you can choose your own 
keys), and it talks about the two-player game, 
which also isn’t available. 

Never mind, it’s easy enough to learn to play 
- but frustratingly difficult to play it well. It’s 
an entertaining game with a high very 
addictiveness rating. Jeffery Pike 



MIXED 


SPORT 



‘Hyper Sports’, Imagine, BBC B, £14.95 
(disc only) 

Four things are tested by Olympic games - the 
speed, and the endurance, of your hands at 
hammering the keyboard; reaction time to 
changing events on the screen (like rapidly 
increasing angles, etc); and accuracy (either by 


hitting a target, or by doing something at a 
precise point such as a take-off line). The very 
best events are those which can challenge all 
four abilities and get you to co-ordinate them - 



javelin-throwing is a good example. But for 
the newer games, new events are being intro- 
duced - and only a few successfully involve all 
the challenges of the best Olympic games. 

The quality of the six individual events in 
Hyper Sports vary enormously. 

By listening to the sound effects, the open- 
ing events - skeet shooting and swimming - 
can literally be played with your eyes closed. 
On the other hand, the archery offers an 
intriguing challenge (the wind speed and direc- 
tion vary, so the event can be different each 
time you play). The triple jump provides a true 
test of co-ordinating speed, angle and timing. 
And the weightlifting is a good challenge to 
your finger muscles - if you can get that far in 
the game! 

The problem is that the central event, 
gymnastics, operates on totally incomprehensi- 
ble principles. 

There just doesn’t seem to be a ‘method’ you 
can master, so your results are completely 
unpredictable. It’s enormously frustrating to 
fail at the gymnastics each time, and be sent 
back to the easy opening events, never reach- 
ing the later, better games. 

And there is no ‘practice’ way of trying out 
the various events; you have to play in se- 
quence every time. 

In the end, I felt those frustrations and the 
easy, boring opening games outweighed the 
really entertaining events. There are three 
good events, two boring and one that’s just 
plain duff - for me, that doesn’t count as 
enough to be value for money.

SATISFYING 


SNOOKER 



‘Steve Davis Snooker’, CDS Software, BBC 
B and B 4- , £8.95 (cassette), £12.95 (disc) 

Here’s your chance to play snooker against the 
Romford maestro, and even beat him. Steve 
‘Interesting’ Davis apparently endorsed this 
program, and it must be said that it’s a pretty 
accurate computer representation of the game. 

The table is illustrated on screen in mode 2, 
with green cushions and a black playing 
surface - which causes a few problems straight 
away, like how do you show the black ball? 
(Answer: a white circle, black inside. Similarly 
the brown is really green and red.) Also, mode 
2 graphics only allow fairly rough-and-ready 
shapes: the balls are chunky crosses. 

Before you start, you select the speed of the 
table (fast, normal or slow), decide whether to 
play against an opponent or the computer or 
yourself (good for practising), then, if you’re 
playing the computer, elect just how good 
your opponent (S Davis Esq) is going to be, 
from 9 (unbeatable) to 1 (frankly pretty ropey). 
When it’s your turn to pot, you use the 
keyboard to position a hairline cross exactly 
where you want to hit the target ball, to define 
the spin and pace of the cue ball, and to fire. 

The results are generally much the same as 
when 1 play on a real table - balls rocketing 
everywhere, the occasional fluky pot, a foul 
stroke every now and again, and a very rare 
brilliant snooker. The computer keeps score 
and does everything else that nice man with the 
white gloves does, respotting the balls, calling 
the fouls, asking if you’d like your opponent to 
play again after a foul stroke, and so on. 

The balls don’t move round the table exactly 
like the real thing but, all things considered, 
the animation is fairly smooth. A bit of sound 
might help: surely it wouldn’t slow things 
down too much to have a click when balls 


collide? It’s quite enjoyable to play, fairly 
frustrating (just like the real thing) and, believe 
me, immensely satisfying when you land Smug 
Davis in an unplayable snooker. 

Jeffery Pike 



LOADS OF 


CHALLENGES 



‘Gyroscope’, Melbourne House, BBC B and 
Electron, £8.95 (cassette) 

Every so often, you come across a piece of 
games software which you suspect was much 
more fun to write than it is to play and here’s a 
case in point. You have to steer a spinning 
gyroscope across platforms and down ramps, 
into holes like those on bar billiards tables 
(hands up those who remember bar billiards). 
When you’ve achieved this, you get another 
screen, with more platforms and more ramps, 
leading to another hole. And then another one. 

The programming is ever-so-clever. The 
screens look solidly three-dimensional and 
your gyroscope behaves just as a real one 
might if you had remote control over it 
reacting slowly but surely to a twitch on the 
rudder (keys or joystick), rolling faster down 
the steep slopes than the gradual ones, trun- 
dling slowly uphill when necessary, and falling 
off the edge if you oversteer. John Nixon and 
David Wain wright are to be congratulated for 
some neat graphics, and a brilliant application 
of three-dimensional geometry and the law of 
gravity. But as for playing the game . . . 

1 just couldn’t get excited about it. I couldn’t 
see why I should want to steer a gyroscope into 
a hole, and thus I didn’t care much one way or 
the other if I made it or not. I’m not sure what 
it is that’s missing, but all the best computer 
games have some in-built compulsive element 
which makes you want to go on playing and 
doing better. This one, clever though it is, 
simply doesn’t. Jeffery Pike 



THE SEQUEL’S 



THE SEQUEL’S 


I 


‘Nightshade’, Ultimate, BBC B £9.95 
(cassette) 

I enjoyed Nightlore, I really did. The advances 
Ultimate made with its ‘filmation’ technique 
were, at the time, amazing. Alien 8 was more of 
the same. It was claimed it had a better plot, 
but it was generally felt to have less going for 
it. This latest offering changes the backdrops 
again, offers a few more nicely drawn nasties, 
but for all that is very much the same as its 
previous two adventure cartoons. 

The cassette sleeve tells of a nightmarish 
village populated by ghouls and ghosties. All 
that can save the Kingdom is a weird little 
fellow in a habit. Guess who controls him? 

The game uses the same 3D effects as before, 
with the interesting development that walls 
containing doorways vanish as you walk your 
hero through. It gives the game a more solid 
feel, and the buildings are very well drawn 
tudor-panelled affairs. 

There’s a motley assortment of meanies, 
some of them brainless and looking like escap- 
ees from a Maurice Sendak book, others with a 
nasty line in zapping you. You have a variety 
of different weapons (bacteria the blurb calls 
them), and most of these work on most of the 
baddies most of the time. 

The colour schemes are pretty dull, using no 
stippling or other screen-enlivening effects, 
and sounds are few and far between. 

The Nightshade cassette comes with a second 
bonus tape, containing a game rejoicing in the 
name of ‘Head Cleaner’. 'This one has very 
poor graphics, no sound (except a peculiar 
rasping from the tape machine while it’s 
loading), and precious little plot. Seriously, 
though, it’s quite a fun package, but it’s about 
time Ultimate came up with something new.

WITH A VIEW 
TO STORAGE 

Alex van Someren delves into Acornsoft’s database ROM 
and decides it’s good value for money 


View Store is the latest ROM offering from 
Acornsoft in its View family of loosely-con- 
nected business software for the BBC micro 
and Master series. Supplied as a 16k ROM, 
manual and utilities disc it supports DFS, 
ADFS and Econet filing systems, although its 
performance with the latter is decidedly unin- 
spiring except when used with the presently- 
unreleased ANFS - I’ll tell you more about 
that later. 

ViewStore is a fairly sophisticated package, 
allowing the computer-literate user to set up a 
good environment for working with 
databases, and it’s certainly one of the best for 
Acorn equipment currently on the market. 

Configuring ViewStore 

Like all general-purpose database systems 
ViewStore needs a significant amount of set- 
ting-up before data can be entered and the 
database put to work. After installing the 
ROM the user must configure ViewStore so it 
can find all the various files needed to run the 
database - it expects to find a database file, a 
format file (controlling the screen and data 
formats) and usually a number of index files. 
Each kind of file must be stored in a different 
directory, each named with an initial letter, eg, 
‘D’ for the database files. The Prefix command 
establishes where the directories D, F and I 
(and others) are found on the current filing 
system, so for example, one might set the 
Prefix for the database files to be “:0.” where- 
upon ViewStore will always search for a 
database file by trying to open “* j. D. database- 
name”. This arrangement is a little unnecessary 
when using hierarchical filing systems such as 
the ADFS or Econet, but can save a lot of 
bother when using ordinary floppy discs. In 
this way ViewStore manages to accommodate 
all Acorn filing systems and any number of disc 
drives with minimal preamble, though a boot 
file is definitely required! 

Once you have set up the system using 
Prefix, ViewStore expects you to estimate and 
enter the amount of space needed by the 
database overall - the number of records you 
expect to have, the number of indexes, their

ViewStorts spreadsheet display mode 

filenames, and the index key sizes - using the 
Setup utility supplied. This process shows how 
ViewStore suffers from Acorn’s past mistakes: 
if, while answering Setup’s questions about the 
expected size of the database, you fail to 
provide sufficiently over-estimated answers, 
the DFS will come up against ‘Can’t extend’ 
errors. On the other hand the manual says that 
the system operates (ie, after setting up) more 
slowly with larger files, probably due to the 
indexing technique used. Since the only cure 
for such errors is to compact the disc, it 
appears DFS users will have to suffer slower 
systems until they upgrade to ADFS, where 
such problems do not occur. 

Finally, before you start entering data, 
ViewStore wants you to tell it the names, types, 
sizes, constraints and prompts associated with 
each field of a record, along with a variety of 
optional information which depends on the 
specific kind of field. Data types available are 
alphanumeric, textual, numeric (eg, floating- 
point) and two date formats (English and 
American). Alpha and text types have a Srroll 
flag’ which allows them to be larger than the 
available screen space. The distinction between 
these two types is abysmally glossed over in the 
manual, and proves to be quite important. 

Numeric data has a decimal places control, 
and all types can have lower and upper limit 
constraints, eg, earliest date or highest letter of 
the alphabet. Each field can have a prompt, 
displayed at the top of the screen when the 
cursor is on that field, and you may also supply 


a value list which restricts the data allowed to 
be entered into the field to entries in the list. 
There are also several options for indexing. 

If this preparation process sounds daunting, 
then rest assured - it is! But, like most 
softwr c, it soon becomes second nature and 
after creating five or six different databases 1 
find the whole process takes about 15 minutes. 

Once the formalities have been completed, 
ViewStore is ready for you to enter data onto 
the screen. ViewStore uses two screens in much 
the same way as View does, Escape toggling 
between them. The data screen can be in one of 
two formats, either ‘spreadsheet’ or ‘card’. The 
former shows one record to a line, with fields 
arranged as columns, and scrolls sideways 
(almost) infinitely to accommodate fields that 
arc not immediately visible. The latter permits 
you to layout fields in a pscudo-cardbox style, 
possibly more useful where you want to keep 
many fields visible at once. This layout must be 
designed with an unpleasantly simplistic editor 
which spoils the card display for me to the 
extent that I don’t bother to use it. 

ViewStore thinks very hard when you enter 
data, a fact exaggerated by the time lag 
between typing things into fields and them 
actually appearing on the screen. While the 
delay is not long in real terms, it is more than 
perceptible and therefore rather irritating. 
That aside, though. I’m delighted to say that 
entering data is simplicity itself. The use of a 
boot file saves time and tears at switch-on, but 
beyond that stage a child could do it! 

Database usefulness 

The ultimate usefulness of any database comes 
from its indexing capabilities, something 
which ViewStore is not short of. An index can 
be created for any field in a record, or for 
several at a time, depending on how they are 
created. You may use the Index utility to create 
a one-off index tor a field whenever you wish, 
but when more data is added the index instant- 
ly becomes out ot date. To overcome this 
ViewStore can maintain indexes on several 
fields at a time automatically, the exact number 
being determined by the filing svstem in use.

BETA-ACCOUNTS £25 

STATEMENT AND ACCOUNTS 
RECEIVABLE MODULE 


This module uses the transaction files created by 
the INVOICE module to prepare statements at 
regular intervals. The statement run is totally 
automated once security backups have been 
completed and will save hours of work every 
month. The Accounts Receivable allows you to 
enter all outstanding debts for an account and it is 
then automatically kept up to date by the invoice 
program. All payments received are entered into 
the accounts receivable file and allocated against 
the outstanding account. 

In addition to the time saving operations 
performed by this module you can also obtain 
valuable management information such as debtor 
lists, which can be pnnted together with telephone 
numbers. It is also possible to query any 
particular account and obtain an up to date 
picture of the position. 


STOCK CONTROL 
MODULE £25 


The stock control module is used in conjunction 
with the invoice program and is updated 
whenever an invoice is issued. It is then possible 
to automatically search the stock file for out of 
stock or re-order level items. Purchase orders can 
then be printed, automatically if required. 

As with the Accounts Receivable there are many 
forms of management information available 
including stock numbers and values both 
numerically and as a percentage figure. This 
enables you to identify slow or fast moving parts 
easily. 

A parts explosion option is also available for just 
£10 extra. 

A twin double sided drive is required for the 
STOCK CONTROL module.

SOFTWARE 


The DFS and NFS can maintain four indexes, 
while ADFS can support nine. 

The speed (or rather sluggishness) of the 
system is directly in proportion to the number 
of indexes being updated, and with more than 
two the delays mentioned above become even 
more disturbing. 

Records may be ordered on screen by means 
of any index (including out-of-date ones), 
allowing instant checks for duplications and 
gaps. The value of this facility should not be 
underestimated, as a corrupt database is a 
useless database! 

Select utility 

Once up-to-date indexes exist, ViewStore al- 
lows more sophisticated record selections us- 
ing the Select utility. This allows you to 
generate either a printed list of a subset of the 
database, or to generate a new database con- 
taining that subset, thereby allowing further 
processing. All the utilities except Select and 
Setup can use such a file as their source data. 

After a few preliminaries Select asks for the 
selection criteria, of which there can be any 
number. Each criterion must evaluate to a 
Boolean value (eg, NAME=“Alex”, whose 
value here is TRUE), and the criteria may then 
be strung together using the Boolean operators 
AND and OR. To permit complex selections 
ViewStore allows the criteria to be entered over 
several lines, and multiple bracketing is per- 
mitted so the order of evaluation can be forced. 
Single and multiple character wildcards are 
allowed, and an option also exists to truncate 
the amount of a field used in a comparison. 

When generating a file of selected data 
ViewStore also asks for the fields by which you 
wish the resulting records to be sorted. Again, 
there can be any number of sort fields, so long 
as ‘the total number of characters used in the 
comparisons is not greater than 250/ whatever 
that means. The sorts can be performed in 
either ascending or descending order. 

I found the Select utility very easy to use, 
though it is fairly poorly documented. The 
distinction between the alphanumeric and 
textual types is that in the former case the 
whole field is used in the comparison, whereas 
in the latter case each word in the field is 
compared individually. In this context 
ViewStore defines a word to be any number of 
characters bounded by spaces. I only discov- 
ered the three lines discussing this in the 
manual as 1 was writing the review, and this 
highlights the lack of a summary of the 


selection commands, a serious omission in 
discussing an area which much of the system 
revolves around. 

The ‘select file’ produced by the Select 
utility can be used by some other utilities to 
produce formatted output and link ViewStore 
with other members of the View family. 

The Macro utility translates a select file into 
a series of View macro lines, one per record, 
which may then be read into View to provide 
data for labels, form letters, etc. Macro simply 
asks the user to enter the order in which the 
fields are wanted in the macro to be generated, 
and requests a name for the resulting file. 

The Link utility performs a similar function 
for transferring data to ViewSheet. Again, you 
may specify which fields you wish to transfer 
and in which order, followed by a filename 
which is usually of the form “V.VSn” (n = 0- 
255) to be compatible with ViewSheet " s Read 
facility. The Link utility is not as comprehen- 
sive as Macro in that it can only transfer 
numeric fields, a little surprising knowing that 
ViewSheet accommodates labelling of rows and 
columns and that the field names are readily 
available from ViewStore. 

No prizes for divining the purpose of the 
Labels utility, which is a short-cut to avoid 
using Macro and then having to go into View. 
The numerous options ensure that nearly every 
size and shape ot continuous label stationery 
can be used, and a nice touch is the ‘Alignment 
print’ option, which allows you to make a mess 
of reams of labels in order to get them aligned 
before printing a full set. Anyone who has 
printed labels more than once or twice will 
understand what a good idea this is! 

The fiendishly useful Import program is 
actually a chunk of Basic and machine code 
which converts foreign data formats into 
ViewStore databases. It requires a good deal of 
preparation before use, such as finding out 
how records are delimited in your source file 
and so forth. I have persuaded it to create 
databases out of everything from View macros 
(the opposite of Macro!) to corrupted ASCII 
text files. It asks you nearly 20 questions before 
it goes off to process your file, and I find it 
hard to imagine any format which it couldn’t 
cope with. Several examples, dBasell among 
them, are included in the manual. It’s not fast 
but it’s a blessing for anyone who is already 
using other database systems. 

Finally, the Report utility is a simple pretty- 
printer which works in very much the same 
way as macros do in View, ie, fill in the blanks. 


Headers, repeated on every page, are support- 
ed as are both textual and numeric blank- 
filling. Basic arithmetic is permitted, and two 
levels of registers are available for performing 
sub-totalisation. Using these registers 
ViewStore will print out sub-totals each time 
the value of a specified field changes, produc- 
ing neatly formatted listings with totals in

Conclusion 

ViewStore is a fairly comprehensive database 
management system, and it fits loosely but 
tidily into the network of data transfers within 
the View family. It is certainly the most 
comprehensive database management system 
available for Acorn equipment that I have 
encountered, but it still has a long way to go 
before we can compare it with some systems 
for other machines - still, what can you expect 
for several hundred pounds less? 

Using ViewStore on the Econet is a complete 
write-off unless you have ANFS or are using a 
file server from SJ Research. The reason for 
this is beyond the scope of this review, but it 
has to do with the history of the Econet 
software. I strongly suggest you try it out 
before you buy it for network use, particularly 
as Acorn currently has no information on 
when the ANFS will be released. 

If you are lucky enough to have an ADFS 
disc system, either floppy or hard, ViewStore is 
very much easier to use. Using it with the DFS 
is a chore which should really be reserved for 
misers and masochists. 

ViewStore is not fast, but if you trade this off 
against its sophistication I think you’ll agree 
that it’s excellent value for money.

MAKE-UP FOR MORTALS 

Tony Quinn relives the joys of working on newspapers in the first of 
two reviews of publishing software 


Two names have been on everyone’s lips for 
the past six months: Mirrorsoft’s Fleet Street 
Editor and PageMaker from Advanced Memory 
Systems (now in a ‘Super’ version which 
doesn’t need the AMX Mouse chip). I’m going 
to deal with these in two parts, with Fleet Street 
Editor coming first and the AMS offering next 
month. They both have major failings which 
decry their ability to achieve their claims, but I 
have no doubt that they are a major step in 
software publishing, and it is yet another 
tribute to the quality of the BBC micro that 
they appear on it first. 

Fleet Street calls to you through advertising 
pages with ‘professional-looking printed mate- 
rials’ and the jargon of newspapers. AMS 
waxes just as lyrical with ‘a revolutionary 
software program that will produce news- 
papers ... to an extraordinary professional 
standard.’ The adverts then go on to quote 
words like ‘phenomenal’ and ‘outstanding’ 
from an Educational Computing review. 

So, after reviewing the hype, what are the 
programs really like? First, they are both 
restricted to an A4-size page (the size of this 


magazine), and I’m still waiting for a paper 
from Murdoch, Shah, Maxwell (under whose 
wing Mirrorsoft lives), or anyone else which is 
that small. Next, they both suffer from appall- 
ing typefaces, the standard of which takes me 
back four years to the crude styles of early 
printers, because text has to be handled in the 
same way as graphics. This means neither can 
use the near letter quality (NLQ) typefaces of 
today’s printers, which is a pity. 

The set-up 

Before you turn to the Advertising Standards 
Authority, let’s go through the capabilities of 
Fleet Street . The software was written for 
Mirrorsoft by Clares, a company renowned for 
programming through its many utilities. The 
manual is an A5 ring binder with a folder 
containing two discs (which are a tight fit in a 
plastic wallet) and a function key strip neatly 
tucked into the back. This is a big advantage 
over PageMaker , as you can literally put Fleet 
Street in your pocket. No ROMs are needed, 
and the program can be controlled from 
keyboard or joystick - but not from a mouse. 


FLEET STREET 
EDITOR 



Figure 2. Result of using the ‘guided tour’ files. Al 
the material except the ‘Groucho’ panel is provided. 
The banner is a ‘stretched’ panel 


The manual is well-written, indexed, and 
full of diagrams, but it has some annoying 
characteristics. The first is a mass of pages on 
topics like newspaper and computer jargon 
and worthy but wordy chapters on the publish- 
ing process. 

I don’t think I’m alone in wanting to get to 
the nitty gritty, rather than skim through what 
I already know. Of course the package is 
complex and sophisticated, so you have to read 
something to get going, but it would be good 
to show people in a more obvious way which 
bits are and are not vital. 

The numbering system for pages and para- 
graphs can be a bit confusing, but it’s been 
done this way so that Mirrorsoft can send out 
new or corrected pages without having to 
renumber the whole manual. 

The first thing to do is to tell the system disc 
what sort of computer set-up you have - 
printer, disc drives, etc. In doing so, you have 
to learn a new set of disc jargon because Fleet 
Street uses ‘flippy discs’ which you actually 
have to turn over. This might be confusing for 
less-experienced users, but Mirrorsoft assured 
me they had had no problems. I got my system 
set up wrong the first time, but it’s not hard to

do it again. My advice to the uninitiated is to 
find someone to help you. You then prepare 
some ‘user discs’ with a very handy format and 
verify utility. 

Once the system is set up properly, your best 
bet is to go through the ‘guided tour’ where 
most of the work is already done for you. You 
create one panel out of the eight which make 
up a page. 

The guided tour 

The tour introduces you to each of the five 
elements in the system: graphics library, stu- 
dio, copydesk, page make-up and preview / 
print. It works like this: you enter the library 
(figure 1), select one of the 200-odd standard 
graphics (I chose Groucho) and save it to disc. 

You then enter the studio, load in the saved 
graphic, play around with it by expanding the 
size (I doubled the height), and save it to disc. 
There are many other goodies in the studio, 
allowing pictures to be altered and even creat- 
ing your own from scratch, but I’ll come to 
these later. Note, though, that pictures can’t be 



Figure 3. The studio for creating or altering pictures 
and headlines. Icons choose pens and fills, disc, 
copying and rotating facilities and pixel editor 

loaded in straight from the library. 

You now leave the art department and enter 
the copydesk. Here you load in the saved 
graphic, and put words and headlines around 
it. The words part of the package I found 
disappointing, as the text editor is crude 
compared to a wordprocessor (PageMaker 
doesn’t have one at all) and you can only get 32 
characters (about five words) onto a panel line 
and there are just 23 lines to a panel. This 
means lots of white spaces when you justify 
text. The typeface is poor, being based on an 
eight-by-eight matrix, whereas printers use at 
least nine by seven. 

You then save your text and graphics which 
is by now a fully-fledged ‘panel’ - the time has 
come to enter the page make-up area where the

apart from Sarah Brown and Groucho from the Graphics Library. Note that the horizontal rules cannot be car- 
ried across the central ’gutter’ between the panels: the vertical rules do join up, though 


designed panel is put in position on the page. 
Once this is done you have a completed ‘page’ 
so you save it to disc. 

Finally, you leave make-up, and enter the 
print section. The page is loaded back in and 
can be previewed, which gives you a rough 
idea of how it will finally look (it’s about half- 
size). Previewing takes about a minute and a 
half, and if you’re happy, printing takes anoth- 
er three minutes. At last you have a printed 


page - my effort is figure 2. Now if that sounds 
convoluted, let me confirm that it is - I would 
be astounded if anyone got it right first time. 
And if you have printer problems (as I did with 
a Mannesman Tally MT85 which has to have a 
line feed set up), you have to go all the way- 
back to the set-up stage! 

After working my way through the tour and 
having a go with the studio, I realised the 
system just didn’t seem to agree with me.

certain colours. Drawing and painting 
underneath any colour combination. Making 
your brush cycle through a defined colour 
sequence. Colour pattern editing. Sprites of 
any size. Animation. Just a hint of how Artist 
is the most highly advanced software package 
yet designed, with features never before seen

SOFTWARE 


There are niggling little things, as with any | 
software, but there are some fundamental | 
design decisions which annoyed me. One was 
the laborious way of saving pictures. There are 
different ways of saving for the sections you 
visit and each one has several stages. 

Readers who use wordprocessors will appre- 
ciate the need for regular saving of text in case 
of pressing Break accidentally, or losing pow- 
er, but Fleet Street makes this a real pain: it’s 
complicated and time-consuming. For exam- 
ple, if your graphic fills the whole screen, it’s a 
real art framing it for saving, and if you go 
outside the page area you have to start again. 
There is no default for saving the whole screen, 
which there should be to encourage regular 
saving. 

The idea of using panels is quite simple, but 
limiting. Each panel is a set size, so if your page 
design doesn’t neatly fit into eight parts you 
are in for some trouble. I had this problem in 
creating the ‘Stun’ page, where I couldn’t join 
up the rules to make the box (figure 4). Of 
course it’s easy to draw in with a pen on the 



[Mfrs sages : 
Panel : MflHX 


Text: 


Figure 5. The Groucho panel has been taken from 
the studio to the copydesk, where the words are 
added. Note the choice of type fonts in the top right 


printout afterwards but goes against the grain. 
Another limiting factor is that the package 
only allows two columns of text {Pacemaker 
allows more). Going back to the newspaper 
analogy, show me a paper working to this rule! 
EEowever, I found out later that Mirrorsoft had 
worked out a way to do it by setting up a 
graphic for each half of a panel, and writing 
over it in the copydesk. 

By getting to know Fleet Street , I’m sure 
many of these limitations will become ‘fea- 
tures’, and in time ways around them will be 
found - for which the promised newsletters 
will be vital. Mirrorsoft is also set to bring out 
three support discs by May. One will contain 
extra graphics, a text font editor and 10 more 
fonts; the second will be full of Walt Disney 



Figure 7. Sarah Brown being ‘touched-up’ inside the pixel editor, which forms part of the studio. The scrolling 


on this has to be seen to be believed 


characters; while the third will be a utilities 
disc. Mirrorsoft is also working on a ‘wire 
room’ with the package linked to a cheap 
picture digitizer and modem. It is this level of 
support from Mirrorsoft (and third parties I 
imagine) that will really get the package going. 

With all this in mind I set out to put the 
system through its paces by doing a mini 
tabloid front page, and the ‘Stun’ page of 



make a page. The Y/N question refers to whether 
the panel is to be ‘stretched’, as in figure 1 


figure 4 was the result. The girl was taken from 
the library and touched up - she originally had 
a chin like Frank Bruno - using the excellent 
pixel editor (figure 7) in the studio (the 
scrolling speed has to be seen to be believed). 


The background was added to form the picture 
for the lead story. I used Groucho for a second 
story and then started from scratch on the 
Flook cartoon. 

The end result 

The end result is neat and impressive, but is it 
any better or quicker than using scissors and 
paste? With long documents I reckon you’re 
better off with a good wordprocessor and 
printer because the text is so much better. 
However, if you want to produce one-off 
leaflets with lots of graphics you can have a 
great deal more fun with Fleet Street , produce 
very clean pages and it’s an impressive package 
for £40. The graphics library and studio are 
worth using as an addition to cut and paste. 

Next month I’ll tackle Super Pacemaker from 
AMS with their Mouse and give a final 
summing up of the merits of these two 
publishing packages. We look forward to 
seeing the results readers can achieve with Fleet 
Street and Pacemaker.

FOUR PLUSES FOR WORDWISE 

Patrick Quick looks at four utility packages for Wordwise Plus 


Since Wordwise Plus was published last year 
more and more ‘segment programs’ (or 
sprogs) have appeared in magazines and many 
users have written their own. They are easy to 
write and can be very useful, so it was only a 
matter of time before packages of utility sprogs 
were published. This review covers four such 
packages, three on ROM and one on disc. 
Watford Electronics’ Word-Aid ROM and 
Beebugsoft’s WordEase disc each offer a mixed 
bag of general-purpose utilities with no strong 
theme. Norwich Computer Services’ Continuous 


Processing ROM ( CP-ROMJ contains a suite of 
sprogs aimed specifically at making it easier to 
spread a document over several disc files. 
Interface Electronics’ Wordwise + + ROM is 
different. Its main offering is extra string 
handling commands for Wordwise Plus , pro- 
grammed in machine code, but it also includes 
a few general sprogs for good measure. 

WordEase 

This 40/80 format disc contains around fifteen 
different utilities, selected from a menu. The 


range is wide and many are good and well- 
programmed with plenty of user-friendliness 
and flexibility, but one or two are a bit too 
slow to be useful. I am already using the ‘auto 
version save’ for this review, and the label 
printing and mail-merge look flexible. The 
‘section renumbering’ automatically handles 
numbered paragraphs of the 5.3.1, etc, format 
and also amends all cross references to para- 
graphs. I don’t know how useful this is likely 
to be to you but I don’t use that type of 
numbering and if I did it would probably be on 
a document too big to fit in memory. 

Beebug has the advantage over the others in 
offering its product on a disc, which allows a 
lot more space for messages and clear prompts 
and a wider range of routines ( WordEase fills 
about 32k of the disc). It was also fairly easy to 
add my own routines into the menu structure, 
especially after using WordEase to expand the 
abbreviated keywords in the menu sprogs. I 
can see myself using this package as the basis of 
my own compilation of sprogs. A poorer 
decision made by Beebug was to put the main 
menu in segment 9. Pressing Shift/f9 all the 
time is a bit dangerous for my liking, f9 being 
so close to Break. I did, though, like the fact 
that Beebug clearly states that users can make 
one backup copy of the disc for their own use. 

Word-Aid 

Like WordEase this package offers a selection 
of sprogs, but this one’s in a 16k ROM which 
rather limits the space available. Slightly fewer 
options are given and many are trivial and 
inflexible. The printer codes, label print and 
mail merge are inferior to the ones from 
WordEase and the continuous processing op- 
tions come nowhere near the sophistication of 
Norwich’s ROM. The only things that scored 
over the others were the multi-copy printing 
routine (I had already written one myself and 
can’t imagine why everybody else left this out) 
and the sorting facility. Overall I found Word- 
Aid insubstantial - I would want something 
much more impressive before sacrificing a 
valuable ROM slot or the cash, especially as on 
ROM you cannot make even minor amend- 
ments to the routines. I have just noticed that 
Watford is offering Word-Aid free with 
Wordwise Plus in their January 1986 advertise- 
ment - at that price I suppose it’s not bad.

REVIEWS 


SOFTWARE/ROMS 


CP-ROM 

CP-ROM contains a suite of sprogs to enable a 
single document to be spread over several files 
on one or more discs. There are two advan- 
tages to this facility: one is that your document 
can be almost any size, limited only by disc 
space rather than RAM space, and second, 
even for a document that fits into RAM, by 
splitting it into smaller sections you can pre- 
view it in 80 columns. The second advantage 
can be obtained for smaller documents by 
fitting a ‘shadow’ screen RAM board (such as 
the Aries B20) or adding a second 6502 
processor. However, neither of these will give 
you much more total space for your document. 

CP-ROM keeps a file called IFLIST on disc 
which contains a list of the files in use, 
including (if necessary) the drive number and 
directory for each file. IFLIST also keeps a 
note of the current file in the list so that when it 
restarts, CP-ROM loads the last file you were 
using. Switching between files while editing is 
easy (but not automatic). Printing, previewing 
and search and replace can be performed over 
the whole document at once. This is not as 
convenient as having a wordprocessor specifi- 
cally designed to edit large documents but it is 
not bad as most large documents break down 
naturally into chapters anyway. 

Basically CP-ROM works as promised. The 
only small problem occurred when printing 
several or all of the files. The current file was 
printed as the version on disc, not the possibly 
different version in RAM, although this RAM 
version was preserved throughout the opera- 
tion. The sprogs are in ROM Filing System 
(RFS) format on an 8k EPROM which seems a 
bit tight now that 16k F^PROMs have become 
so much cheaper. 

In fact CP-ROM has just been replaced by 
CP-ROM2, offering 16k for £25, featuring 
multiple disc documents of unlimited length, 
80-column preview regardless of file length, 10 
pages of help information, improved preview- 
ing, printing and formatting facilities, and 
enhanced file list manipulation. 

Wordwise + + 

Wordwise + + (aka String Extension ROM) 
contains a set of functions to extend the string 
handling in Wordwise Plus sprogs which are 
made available just as though they were in the 
Wordwise Plus ROM. Wordwise + + works inti- 
mately with the Wordwise Plus ROM, intercept- 
ing the error vector, so you must have the 
correct version to match your Wordwise Plus. 

The 24 functions offer substring (including 


LEFTS, RIGHTS and MID$), padding, search 
and replace operations on strings (you can do 
these things in Wordwise Plus but they are 
slow). All in all they seem to be a well chosen 
set of enhancements to Wordwise Plus's string 
handling facilities. As an example, the function 
LPAD$(BS, U :”,10) in sprog 1 below means 
‘pad out B$ on the left with colons to a total 
length of 10 characters’, ie, B$ becomes 
“:::::HELLO”. Sprog 2 does the same job 
using standard Wordwise Plus commands, while 
sprog 3 executes the empty loop to find more 
precise timing figures. 

The timings (in milliseconds per loop) are: 
sprog 1 = 185ms; sprog 2 = 1045ms; sprog 3 
= 73ms. Thus the LPAD$ loop took 112ms 
whereas the ‘straight’ Wordwise Plus version 



WordEase: well-programmed and flexible 

took 972ms, over eight times longer! You 
cannot expect an eight fold improvement in all 
cases but this ROM should speed things up 
considerably as well as making 
‘sprogramming’ easier. 

Wordwise + + also has four ‘star’ commands 
and six utilities in RFS format. The star 
commands offer function key definitions, sin- 
gle key file selection from disc (nice, especially 
the auto-boot option), alteration of default 
preview mode (why?) and printout of all 
Wordwise Plus variable values. Five of the RFS 
utilities are sprogs - in particular, there is a 
disassembly labeller. I’ve wanted one for years 
and have never seen one anywhere else. The 
routines for label printing and mail-merge are 
rather minimal. The last RFS file is a short 
machine code routine to make a Brother HR1 
printer produce exclamation marks. 

I am told that copies of these RFS files, 
together with a few more utilities, are due to be 
put onto a disc which will be available soon at a 
nominal cost of £1.50 inc. This disc is no use 
without the Wordwise + + ROM as the new 
string facilities are used. The sample I have 
been sent shows a similar range of utilities to 


the Watford and Beebug offerings except, of 
course, that the string extensions are used to 
give shorter, faster utility sprogs. 

Overall 

I was pleased to find that the manuals for all of 
these packages were fairly clear and easy to use 
although the CP-ROM manual was wordy. 

These utilities are the first examples 1 have 
met of RFS files and I am astounded at how 
slowly they load! Normal ROM utilities 
(Wordwide Plus, Disc Doctor , etc) are extremely 
fast but RFS files seem to use a separate ROM 
service call for each byte read. A hard disc over 
a network should be much faster than RFS 
files. WordEase is not constrained by lack of 
space and is easily amended; neither does it use 
up a valuable ROM slot in your Beeb. 

On the other hand, with the ROM based 
packages you do not have to find your utility 
disc before starting or keep copies on each 
wordprocessing disc you have. 

None of these ‘ Wordwise Plus assistants’ will 
work fully over a network. Both Word- Aid and 
WordEase select the discs for you with 
*DRIVE commands. However, it should be 
possible to amend WordEase to avoid this and 
to keep the main utilities in a library directory. 
I don’t know what Beebug’s attitude would be 
to this but I believe it is generally willing to 
consider network usage of its software. All 
three ROM-based packages reselect disc (with 
*DISK) after loading utilities from ROM. The 
main features of Wordwise + + work complete- 
ly within the ROMs, so a network should 
present no problems. 

In summary, then, I cannot recommend 
Word- Aid as it is bettered in almost all respects 
by the others. Each of CP-ROM and 
Wordwise + + attack their chosen area accu- 
rately and can be recommended if you feel the 
need for their particular facilities. WordEase , 
although rather pricey for a fairly straight- 
forward set of utilities, should be a good buy, 
especially if you can adjust the routines to suit 
your own requirements.

The Concept Keyboard* has 
been developed specifically to help 
secondary teachers involve their 
students in interactive projects. 

Designed for use with BBC B 
micros, the keyboard is touch- 
sensitive and user-friendly. 

A variety of software programs 
accompanied by special overlays 
gives the teacher immediate access 
to practical and interesting projects. 
Four new programs have recently 
been added to our list: 

D.C. Meters 

A practical program which 
simulates a direct current electricity 
meter. The student can explore the 
intricacies of D.C. power systems 
through an overlay and various 
different screens. 

Heat the House 

Students are introduced to 
process control application by a 


cross-section 
house with several 
options. Through 
unu closing radiator valves, 
in traducing lagging orfitting double 
glazing a better understanding of 
heat flow is achieved. 

Gumshoe Logic 
This graphically illustrated 
puzzle program is designed to be 
both entertaining and educational. 
It will encourage logical thinking by 
means of mental detective work, 
introducing students to gangster- 
style characters and some 
interesting situations! 


Small Mammal Survey 

This interesting project 
relates to the habits of 
smaller mammals in their natural 
habitats. The student is able to set 
traps, mark the animals and release 
them in order to obtain information 
about population distribution, 
growth and habits. 

Several weeks of intensive 
fieldwork would normally be 
required to undertake this type of 
study. The Concept Keyboard may 
also be programmed for special 
class projects of any type, involving 
students in the preparation of 
overlays and input of ideas.

TURN YOUR BBC COMPUTER 
INTO A REAL TIME IMAGE 
PROCESSOR WITH THE IMAGE 
III FRAME STORE 



IMAGE III is a high resolution Frame Store which can capture and display 
pictures in real time from any 625/525 line video source. Once captured in 
the 512 x 512 frame memory, the computer can access the stored image for 
processing or manipulation. The store utilises 6 bit A/D and D/A converters 
to give up to 64 grey levels per pixel. A major feature of this store is that if a 
lower resolution picture is selected then the store can be partitioned to store 
multiple pictures, eg for 256 * 256 resolution, four pictures can be stored. 
This allows the computer to compare two or more pictures captured from the 
same or different video sources. 

The IMAGE III Frame Store turns your BBC computer into a low cost 
image processing system and opens up a range of possibilities such as 
Robotic Vision, Medical Imaging, Factory Inspection, Microscopical Analy- 
sis etc. Alternatively the store can be used in applications where picture 
data is arriving slowly, eg weather satellite transmissions, ultrasonic 
imaging, enabling the user to have a steady display without the need for 
long persistence display services. 

IMAGE III plugs directly into the 1MHz bus on the BBC micro and is 
supplied with a comprehensive software package which demonstrates the 
features of the store. 

Price: £1,990 plus VAT 

IMAGE III is also available for the IBM PC and Apple computers. 

IMAGE processing software package £590 plus VAT.

Micro unit on the move 


Micro- Robotics of Cambridge has 
developed a new micro controller. 

This compact device may be 
programmed from a variety of 
computers and then left to operate 
independently. It has its own 
high-level resident language, de- 
signed specifically for control ap- 
plications, which is simple to learn 
for anyone with previous Basic or 
Logo programming experience. 

The unit runs independently of 
a power source since it carries 
batteries, which means that where 
portability and movement are im- 
portant the unit has the flexibility 
to go where computers cannot. 

Teachers have long bemoaned 


children’s preconception that a 
computer is a box with a keyboard 
on it. 

This unit will help to dispel that 
myth and its great versatility will 
be proven by the flood of applica- 
tions it will generate. 

Optional extensions to the con- 
troller include a 20 character de- 
tachable keyboard, 16 character 
two-line LCD display, a range of 
sensors, servos, buzzers, the Snap 
EV1 camera, stepper motor driver 
and many more. 

It costs £195 and details are 
available from 264 Newmarket 
Road, Cambridge CB5 8JR. Tel: 
(0223)32310. 



Micro-Robotics micro controller is suitable for use in a variety of situations

Teach-in on telephones 


How do you teach a child how to 
respond to an emergency? W hat is 
the most effective method of 
training in the use of telephones? 

Primary Programs think it has 
the answer with Photiin , its tele- 
phone skills package, developed 
in conjunction with MEP. The 
package comes complete with a 
British Telecom telephone (dial 
variety) and a connector to the 
analogue port. The software may 
be used with a Concept Keyboard. 


A variety of tasks is undertaken 
including accurate dialling, deal- 
ing with emergencies, using direc- 
tories and information services. 

At all times the computer is 
used not only to monitor the 
child’s accuracy but also to pro- 
vide the motivating force behind 
the simulation. A payphone op- 
tion is also available. 

Details are available from Pri- 
mary Programs, Claypits, Debden 
Road, Saffron Walden, Essex. 


The Slomo Micro Speed Control- 
ler from Nidd Valley Micro Prod- 
ucts enables teachers to slow 
down and freeze programs. It 
operates by giving interrupts to 
the central processor and fits into 
the Tube interface on the under- 
side of the machine - for people 
with second processors an adaptor 
links the two devices. A version is 
also available for the Electron. 

Teachers will find this of great 
use in a variety of applications: 
where a pupil has special needs 
and is unable to cope with the 


frenetic speed required for some 
programs, this device will allow 
him or her to work at an even 
tempo. Moreover, when demon- 
strating using a computer to a 
class, a teacher often wants to 
pause and freeze the action. 

Mice 

Also available from this company 
are two mice - the Anamousc and 
the Digimouse. The first is con- 
nected to the analogue port and is 
easily programmed using the usu- 
al ADVAL commands. The sec- 
ond is more conventional and will 
be compatible with both the 
AMX Mouse and Wigmore 
Megamouse software.

Highlight in 
the spotlight 

Highlight Software is the featured 
company in our small software 
houses section this month. It pro- 
duces a wide range of primary 
materials which are programmed 
to a very high standard - in terms 
of maths, road skills and reading 
and language development these 
deceptively simple programs are 
some of the best I’ve seen. 

Most are aimed at the seven to 


1 1 age range. The principle is that 
the ideas should be presented in a 
stimulating and visually attractive 
way. For this reason nearly all the 
programs are ‘arcade’ in style. 

Also, the programs have more 
than one level of difficulty, de- 
signed to allow children to devel- 
op their skills in a practical fash- 
ion. For example, in the 
Adventurous English package which 
deals with positional adverbs, the 
simple exercise used in the first 
part of the program is turned into 
an adventure game-cum-logic 
puzzle in the second. The Read 
Right Away series takes novel ap- 
proaches to vocabulary and spell- 
ing and reinforces principles be-

Wordprocessing made easy 


Three primary wordprocessing 
packages have just been launched 
which each copes with the prob- 
lems of introducing children to the 
basic concepts of editing and text 
handling in a totally different way. 

WordPlay from BBC Soft uses 
animation to make the available 
facilities attractive to users. For 
example, when right-justifying the 
text Fve the Elephant marches up 
from her place at the bottom of 
the screen and tugs the padded 
text into position. Other charac- 
ters left-justify, control deleting, 
move and copy text, push lines up 
and down or implement the filing 
utilities. The whole package 
comes complete with a spelling 
checker and dictionary editor. 
WordPlay is available for BBC B 
and Electron on cassette, transfer- 
able to disc. 

Probably the most sophisticat- 


The entire database of educational 
software compiled by Nick Evans 
and featured in part on pages 159 
to 170 is available from Acorn User 
in a variety of formats at £5.75. 
The datafile contains over 1700 
records and is available for the 
ViewStore database. It may also be 
obtained as a text file for the View 


ed package of the three is Pendown 
from Logotron, which uses both 
chip and disc to give a wide 
variety of facilities. 

Pendown incorporates not only a 
spelling checker and dictionary 
but also a ‘tree’-based planner 
enabling the child to consider the 
title of the piece being written, the 
separate paragraph headings, ele- 
ments within those paragraphs, 
sub-elements of those elements 
and so on to a depth of 10 levels. 
The whole plan may then be trans- 
ferred into the wordprocessor 
with indentations marking the 
level being worked at. 

On-line help 

While the child is engaged in text 
creation there is on-line help with 
both vocabulary and spelling from 
the dictionary and its accompany- 
ing thesaurus facility. 


wordprocessor which can be con- 
verted into a datafile for a number 
of other database packages with a 
utility for ‘grabbing’ records. 

The disc comes complete with 
the address list of publishers and 
instructions as to the most appro- 
priate methods for searching the 
package with ViewStore . 


Delete is effective in two modes 
- auto-repeat or single character. 
In single character mode the char- 
acter above the cursor is deleted. 

Print out of the final product is 
always important. The Pendown

to be defined and comes complete 
with a Jumbo font which pro-

EDUCATION 

FIRST TRACK YOUR SATELLITE... 

Do you want to keep your eye on the ‘eyes-in-the-sky’? 

Then why not use your micro to keep track of them? 


A few keen amateurs have been involved in the 
tracking and receiving of data transmitted 
from satellites for many years, notably using 
the TIROS series of meteorological satellites. 
Recently the field has expanded to include 
satellites involved in scientific experiments and 
radio-amateur work which can be categorised 
as: polar orbiting weather satellites - the 
NO A A and the METEOR series; geostation- 
ary weather satellites - METEOSAT; scientif- 
ic/radio-amateur satellites - the UoSAT series; 
and radio-amateur satellites - OSCAR and the 
RS series. 

Each category has its own merits. For 
example, the NOAA, UoSAT and OSCAR 
spacecraft have the advantage of being fairly 
inexpensive to track in terms of ground-station 
facilities; however, they are only within range 
of the UK for relatively short periods each day. 
The geostationary METEOSAT is more ex- 
pensive to receive because of its ultra high 
frequency (1.6945GHz) radio transmissions, 
but it has the advantages of producing very 
high quality pictures and of being available all 
the time. 

Getting started 

You don’t need to be a technical wizard or 
have masses of expensive equipment to get 
started. All that is required for a basic satellite 
tracking-station is a radio- receiver tuned to 
one of the satellites, a suitable aerial (possibly 
home made), a tape recorder to record any 
transmissions received and a micro. 

The particular equipment you use will partly 
depend upon the satellite you wish to track. 
We cannot go into great detail here, but have 
provided a list of some suitable equipment and 
further reading at the end of this article. 

To save listening to ‘white noise’ for hours, 
you’ll need some way of predicting when a 
satellite is within radio-range, and although 
this can be done manually, the micro will give 
you a fast and accurate fix on the satellite’s 
position as well as providing a means of 
decoding and displaying received data. 

Apart from the special case of a satellite in a 
geostationary (geosynchronous) orbit, all satel- 
lites appear to ‘rise’, move across the sky and 
‘set’. Thus they will not always be in the sky or 
within your radio-range. 

If a satellite orbits the Earth at a height of 
approximately 36,000km its orbital period 


Craig Underwood and Eric Twose 



equals 24 hours. If such a satellite is in orbit 
over the equator, it always appears to hang 
over a fixed point on the Earth’s surface. This 
is very useful for communications satellites and 
some weather satellites as they can give contin- 
ual radio or photographic coverage of almost a 
third of the Earth’s surface. 

To receive signals from a geostationary 
satellite, such as METEOSAT, all you do is 
point the aerial at the part of the sky where the 
satellite appears to hang. 

Another important class of orbits is the 
polar one (as used by UoSAT, NOAA and 
most Earth imaging satellites such as 
LANDSAT). Here, the satellite is launched so 
its orbital path takes it close to the poles on 
every orbit; hence the name. The advantage of 
this is that as the Earth rotates under the 
satellite, virtually the whole surface of the 
Earth comes into view. This is particularly 
useful for Earth-imaging satellites which can 


by using tables, published by AMSAT-UK 
(see the references panel at the end of this 
article, page 151). 

AMSAT-UK’s ‘OSCAR-locator’ uses the 
information within these tables and provides a 
low-cost method of predicting the orbit of a 
satellite. The OSCAR-locator is a circular 
cardboard map representing a view of the 
Earth from above the north pole. 

A movable ‘D-shape’ represents the 
generalised path of a polar-orbiting spacecraft 
over the northern hemisphere. This is free to 
move about the centre of the map, so it can be 
set up as indicated by the data in the tables to 
predict whether the satellite will come into 
range of the UK on that orbit and, if it does, at 
what time. 


Complex orbits 

The OSCAR-locator is just one method of 
track of satellites. For more complex 


thus photograph the entire globe. These polar- 
orbiting satellites will pass within range of a 
ground-station in the UK four to six times per 
day. These passes occur in two groups, sepa- 
rated by approximately 12 hours. In one group 
of passes, the satellite will appear to be ‘ascend- 
ing’, ie, travelling from the equator, towards 
the north. In the second group, (half an Earth 
revolution later) the satellite will appear to be 
‘descending’, ie, travelling from the north 
towards the equator. These times can be found 


orbits, like that of OSCAR-10 (which is a very- 
eccentric ellipse), there are some excellent 
computer programs available. AMSAT-UK 
can advise on suitable software. 

Getting a computer to perform the same 
task as the OSCAR-locator is fairly straight- 
forward, but a full blown orbital prediction 
package requires a lot of 3D co-ordinate 
geometry and a knowledge of the effects of 
atmospheric drag. 

Tracking any of these satellites will require

EDUCATION 



some form of antenna but a ‘long-length-of- 
wire’ will only give a good signal with the 
Soviet RS (Radio Sputnik) satellites, which 
transmit on the comparatively ‘low’ radio- 
frequencies of 29-30MHz. All the other space- 
craft mentioned transmit at much higher fre- 
quencies and other kinds of antenna are more 
effective. Each category of satellite requires its 
own antenna, whose shape and dimensions are 
determined by the frequency and polarity of 
the radio signals transmitted. Signals from the 
UoSAT-1, UoSAT-2 and OSCAR-10 space- 
craft can be received using an antenna designed 
for 144-146MHz operation (the 2m band), 
while the NO A A series need one that works in 
the 136-138MHz band. 

Unfortunately, METEOSAT transmits on a 
very different frequency - 1694.5MHz - for 
which it is difficult to make a conventional 
antenna with sufficient gain, so METEOSAT 
is usually received via a dish antenna. Such 
systems are available commercially and often 
have a ‘down-converter' so they can be 
plugged into a NOAA-tvpe, 137MHz receiver. 
However, these systems tend to be expensive. 

The simple dipole is a basic radio-wave 
detector. In practice, the dipole is made out of 
two quarter-wave lengths of tubular 
aluminium mounted end-to-end with a slight 
physical separation and insulated from one 


another by the plastic mounting. The external 
screening braid of the co-ax(ial) antenna 
downlead is connected to the end of one 
element, while the inner signal core is connect- 
ed to the other. 

You could easily make such an antenna 
yourself. Or perhaps someone has an old VHF 
antenna tucked away which can be dismantled 
and cut to suitable dimensions. 

Increasing the gain 

The dipole has a low gain which means that 
only strong signals are detected, but it has the 
advantage of being omni-directional so it may 
be permanently mounted. To increase the gain, 
more ‘parasitic’ elements can be added. Unlike 
the active dipole, these are made from single 
lengths of narrower gauge aluminium and do 
not need insulating from the tubular 
aluminium antenna boom. The more elements, 
the higher the gain and the more directional 
the antenna, so high-gain antennae need to be 
steered so they actually point at the satellite as 
it passes. 

In many ways, at VHF and UHF, the helix is 
an ideal aerial for satellite tracking as it’s 
circularly polarised and easy to build (a plastic 
drain-pipe, some dowelling and a length of 
wire is all that’s needed it works very well!). 
The more turns, the more directional and the 


higher the gain; the fewer the turns, the less 
gain, but the less accurate you have to be in 
pointing the antenna. For example, with about 
two turns, the antenna can be permanently 
mounted pointing up and it will then pick up 
most passes. 

Another bonus of the helical design is that 
an antenna tuned into UoSAT will also work 
well with NO A A, provided you can easily 
rewind the helix the other way. This is because 
the radio signals transmitted by both spacecraft 
come down a bit like a corkscrew and whereas 
NOAA is a right-handed ‘screw’, UoSAT is 
left-handed. 

Dish antennae are only of use with the UHF 
transmissions of the geostationary 
METEOSAT. You could make a one- or two- 
metre dish from glass fibre and chicken wire/ 
kitchen foil. 

You can pick-up UoSATs 1 and 2 using a 
hand-held 144 146MHz narrow band FM 
‘walkie talkie’ receiver (costing under £50) and 
by having a simple whip antenna. 

Such a receiver allows you to listen to the 
‘Dalek-like’ digitalker on board the UoSATs. 
This is a computer-synthesised voice which 
‘speaks’ a series of numbers representing the 
status of the systems on board the spacecraft. 
However, if you are interested in actually 
recording the digitalker’s spoken telemetry or

ARE YOU GETTING THE MOST FROM YOUR DOT MATRIX PRINTER AND DISC DRIVE? 

DIAGRAM is a new program which really exploits the full potential of the BBC micro and will 
enable you to obtain printouts of a size and quality previously unobtainable from your system. 

Originally designed for producing large circuit diagrams, DIAGRAM has now been improved to the 
point where it is invaluable for anyone who wishes to produce large areas of mixed graphics and 
text, and has many of the features normally found only in very expensive text/graphics 
processors. 

DIAGRAM utilises a unique method of storing information on disc which allows not only very large 
diagrams to be created, but also allows rapid ‘scrolling' of the screen both horizontally and 
vertically over the full area of the diagram. 

The hard copy printout options available with DIAGRAM are second to none, and use is again made 
of the unique disc storage techniques to produce both horizontal and vertical printouts in various 
sizes down to probably the smallest high definition printing you have ever seen from your printer

the two satellites’ digital tone-encoded tele- 
metry, you should check that the receiver has 
an audio output/headphone/extension speaker 
socket, so you can take an output to a cassette 
recorder or portable reel-to-reel machine. 

A simple receiver-antenna system such as 
this will get you started and will be sufficiently 
sensitive to allow you to collect data. Some 
days during the week one pass will be close 
enough to allow reception of a good deal of 
data on that pass and some data on the earlier 
and later pass; on other days, two passes will 
fall either side of your tracking station, so 
you’ll be able to get a fair amount of data from 
these two passes. 

However, if you want to pick-up more data, 
more reliably, you’d be advised to get a better 
receiver. Around £ 60 will buy you a 2m 
narrow band FM receiver that looks like the 
sort of CB rig mounted under the dashboard of 
cars. The only thing about these receivers is 
that they’ll only allow you to pick up UoSATs 
1 and 2. 

The NO A A series transmit at VHF on the 
136MHz band - see ‘Downloading the Weath- 
er’, Acorn User August 1984, for more details. 

If you are prepared to pay a price of 
between, say, £150 and £700, there are receiv- 
ers and transceivers (transmitter plus receiver) 


on the market which will allow you to cover 
most of the current satellites. 

A number of manufacturers are now pro- 
ducing ‘complete systems’, ie, aerials, receivers 
and decoders, for some of the satellites men- 
tioned. These might well represent a good 
entry point into satellite tracking - as always, 
though, it pays to shop around. 

A practical set-up 

The Ground-Track Project was set up at 


Scarborough Sixth Form College and got 
involved with satellites in January 1984, when 
we received a booklet from the University of 
Surrey about UoSAT-1. To start with, we 
bought a receiver for about £50 and made up a 
crossed-dipole aerial out of wood and welding- 
rods, which was connected to the receiver by a 
length of standard TV co-ax. With this basic 


system, UoSAT-l’s telemetry and digitalker 
was picked-up for the first time on February 29 
1984. A quick program was then written to 
produce experimental results from the num- 
bers which were keyed into a BBC micro while 
listening to digitalker. 

It was quickly realised that the path of the 
satellite had to be predictable, as up until that 
time, the receiver had to be left on all the time, 
as we had no idea when the satellite was within 
range. It was also found that getting results 


from digitalker wasn’t very satisfactory, as it 
took a few minutes for the telemetry to be 
‘spoken’. During this time, there were many 
bursts of noise which made it difficult to 
understand the electronic speech. 

On the other hand, the digital telemetry was 
transmitted continuously, each ‘frame’ of data 
lasting five seconds. This would provide far 
more data per pass, and be more error-resilient, 
but it needed some additional hardware before 
the signals could be decoded. Thus, shortly 
after picking up the first few signals, we began 
to write an orbital prediction and a telemetry 
data handling package. These were to become 
Sat-Pack. 

Perfect reception 

Meanwhile, UoSAT-2 was launched and as its 
signals were directly compatible with the BBC 
micro, we concentrated on this spacecraft. We 
were also lucky enough to be loaned a cross- 
polarised yagi aerial by the Physics Depart- 
ment of the University of York. Although 
bulky, this enabled us to pick up the satellite’s 
signals close to the horizon and achieve pass 
times in excess of 15 minutes with mostly 
perfect reception of data. 

It soon became clear that if we were going to 
stick with a high gain antenna, some form of 
remotely-controlled system was required to 
track the spacecraft. To this end, an ex-outside 
broadcast camera mount was bought for £45. 

After about a year’s project work, we’ve 
managed to get this system under the com- 
plete, real-time control of a pair of BBC 
micros. One runs the Sat-Pack orbital predic- 
tion package which outputs tracking data via 
the RS423 port, while the other runs our 
control program, taking this data in and 
tracking the aerial automatically.

data can be picked up as a 1200 baud Audio 
Frequency Shift Keying (AFSK) signal, very 
similar to the signals which encode BBC micro 
programs onto cassette tape. By feeding these 
signals into the cassette or RS423 port of the 
Beeb from a tape recording or in real-time, 
they can be translated into numerical data 
which are analysed for errors and stored on 
floppy disc as a ‘processed data file’. This can 
then be displayed in a variety of ways. The

We started satellite tracking for an initial cost 
of about £50. Our present system, excluding 
computers, is worth about £360. This includes 
an aerial and receiver for NO A A, a high gain 
aerial, rotator and receiver for UoSAT-1 and 2, 



Getting ready for pictures: students fit the yagi antenna on the camera mount 


Recently, work has restarted on UoSAT-1. 
We are testing the prototype of a system called 
Astrid (produced by MM Microwave Ltd), 
which consists of a simple dipole aerial, con- 
nected to a receiver/decoder which has the 
ability to control a cassette recorder. The on- 
board decoder produces TTL signals from 
both UoSATs and plugs into any RS232- 
compatible port. On our system, it is linked to 
the RS423 port on the BBC micro, which is 
running the Sat-Pack telemetry handling/ 
graphing packages. 

We are also beginning to investigate the use 
of satellite weather pictures received from 
NOAA. W'e have a Cirkit weather receiver 
(about £50) connected to a turnstile aerial 
(from Halbar). 

This is mounted on the roof, pointing up. It 
is found that the signals are only strong for a 
couple of minutes on a good pass, so we really 
need a pre-amp, or a steerable, high-gain aerial. 
The pictures are recorded on the BBC micro 
via the Unilab interface. 

The Sat-Pack package currently comprises 
three discs. Orbital Prediction is a very powerful 
suite of programs designed to locate the 
position of any satellite (including those of 
high orbital eccentricity) and to plot its 
ground-track so the user knows exactly when a 
satellite is within range of their receiver. 
Information can be displayed in a variety of 
forms including tabular ‘Whole Earth’ Merca- 
tor Projection, Northern Hemisphere Polar 
Projection and European Theatre Projection. 
Data is also sent to the RS423 serial port or disc 
file to allow control of a tracking aerial. 

UoSAT-2 Telemetry is a suite of sophisticat- 
ed data handling programs, specifically written 
to decode the telemetry transmitted by the 
University of Surrey’s satellite, UoSAT-2. This 


processed data file has a simple format so the 
user can write his or her own data handling 
routines to complement the package. 

Graphics Disc is a suite of programs allowing 
the user to graph the telemetry data generated 
by the second disc, and to look for data 
correlations. 

Sat-Pack is already in use in many schools 
and colleges and is rapidly becoming the 


Astrid for the UoSATs plus the complete Sat- 
Pack software (three discs). That is, for less 
than the cost of a BBC micro, we can track 
most of the satellites generally available, pro- 
viding work in computing, electronics, control 
technology, physics and geography. 

You don’t have to be a technical wizard to 
get started and satellite tracking is not only 
educational but also great fun!

EDUCATION 


VISION OF 
THEFUIURE 

We explore the subject of computer awareness and look at 
the need to teach children the facts of computer life 


Chris Dr age and Nick Evans 


‘Why “computer awareness’? What’s so spe- 
cial about the computer that we need to be 
made aware of it?’ These questions are often 
thrown at computer enthusiasts who try to 
persuade their colleagues, especially in school, 
to realise the role that the computer can play in 
their work. In rather stilted terms we can 
mention ‘pen awareness’ and ‘chisel awareness’ 
especially if we talk about them as tools for 
performing certain tasks, ‘chalk awareness’ and 
‘overhead projector awareness’ are ones that 
should be within every teacher’s experience. 
The computer as a tool, for children and 
adults, inside school and out, is becoming of 
vital importance. This is reflected in the grow- 
ing numbers of packages designed for teaching 
children the facts of computer life and bringing 
their teachers’ methods more up-to-date. 

Short-term problem 

The problem with computer awareness is that 
it should be a short term problem. Even w'ith 
the rise of the computer in every aspect of our 
lives many people are still unaware of its 
possibilities. They need training. Children too, 
especially in the upper parts of the junior and 
throughout the secondary school, do not have 
any depth of knowledge about the computer 
unless they have been trained. However, if you 
take the average eight or nine-year-old in the 
class of a ‘computerate’ teacher and ask them to 
use a program, awareness of the way things 
work, the setting up of the machine, the layout 
of the keyboard and a general familiarity and 
air of unconcern becomes immediately notice- 
able. This child is already ‘computer-aware’. 
He or she will not need a computer awareness 
course as it is at the moment - computer 
studies, perhaps - the computer already is a 
normal part of everyday life. 

Every time the school computer is used it 
builds on teacher’s and pupil’s awareness of the 
micro’s capabilities and shortcomings. Both 


children and teachers need to understand what 
micros are, what they can do and how they do 
it. This is an area vital to the primary school, 
where, for a variety of reasons, many teachers 
are still very unaware of the power of the micro 
in aiding learning. Any way the technology can 
be de-mystified, made ‘more friendly’ and can 
be seen to further children’s learning in the 
classroom must be welcome. 

For very young children the concepts relat- 
ed to understanding the role of microcomput- 
ers are too complex. It’s unnecessary to 
formalise their computer understanding be- 
yond actually sitting them down and letting 
them interact with good software which relates 
to their everyday experiences. By the middle or 
top of the junior school, however, the situation 
is different. When presented in the right way, 
children do begin to understand the concepts 
involved, and it’s at this level where two very 
successful resources come into their own: Using 
your Computer from BBCSoft/BBC School Ra-

dio and The Micro at Work from Granada TV/ 
GSN. Adopting two differing approaches, 
both these packages are extremely valuable in 
the primary school. 

Usingyour Computer first appeared two years 
ago when it was broadcast as Introducing Science 
Extra. Its Computer Synchronised Audio 



(CSA) approach is the brainchild of Arthur 
Vials and Fred Harris (of Micro Live fame). It’s 
a technique which combines an audio voice- 
track with software to provide a unique audio- 
visual presentation (see Education News in the 
February ’86 issue of AU). This approach is an 
instant success in the primary classroom. 

BBCsoft now presents the broadcast and 
software tapes with a comprehensive manual 
which contains the scripts for each of the four 
topics, including In the Picture; Does it 
Think?; Basically Speaking; and Bags of Chips. 

I decided that this package would be an 
excellent opportunity to help a computer-shy 
teacher and her 10-year-old pupils get to grips 
with the school’s BBC micro. The teacher 
concerned worked through each of the CSA 
presentations herself before involving the chil- 
dren, which proved very valuable as she learnt I

EDUCATION 



‘so much about computers’ it gave her confi- 
dence to introduce the micro into her teaching. 
With the children in groups of four, she set up 
a cassette recorder with a junction box and four 
headphones attached, which enabled the group 
to work silently without distracting the rest of 
the class (I had previously turned off the Beeb’s 
sound output by *FX210,1). When every 
group had completed the first presentation 
they began the next. It proved a very stimulat- 
ing and rewarding experience for all con- 
cerned. My only criticisms of an otherwise 
excellent package are the desperate need for a 
tape-to-disc copier routine to handle transfer 
to disc storage, and a way of silencing the 
sound output from the computer. 

Computers at Work, also by BBCSoft, will 
provide a valuable follow-up for this class. 


as a ‘visit’ to a particular location where 
computers are at work. They illustrate how 
computers provide solutions to particular hu- 
man problems, emphasising the interaction of 
humans with computers and the benefits of 
computerisation. Each programme illustrates 
how scaled-down versions of featured applica- 
tions can be handled in the classroom. Al- 
though they will have been broadcast by now, 
a compilation video will be available from 
Granada - alternatively your local teacher’s 
centre may have recorded the broadcasts. 

As each topic is independent of the others, 
the broadcasts can be regarded as starting 
points from which a number of activities can 
evolve - the series booklet provides a wealth of 
suggestions for developing the topics and 
providing follow-up activities. 


Using the same CSA format, it is also aimed at 
nine- to 12-year-olds. It looks specifically at 
two of the most important and exciting appli- 
cations of computers: robots and information 
technology (wordprocessors and databases). 
Children familiar with the former pack will 
undoubtedly look forward to the latter. 

How computers are used 

Granada TV has put together a particularly 
exciting package of TV broadcasts and com- 
puier software called The Micro at Work which 
is aimed at the top end of the primary (lower 
secondary) school. A series of 10, 15-minute 
broadcasts serves as resource material for 
teachers wishing to introduce aspects of com- 
puter usage into the curriculum. Unlike the 
BBCSoft packages, the stress is on how com- 
puters are used, not how they work or are 
programmed. The broadcasts can be regarded 


Three packs of software are available sepa- 
rately. The first and third packs provide 
excellent simulations: Travel Agent is particu- 
larly useful as the whole class can be involved 
in planning and describing their ‘holidays’, and 
Design A House is an impressive and outstand- 
ing piece of software which one would not 
expect to find as part of a series. The two disc 
pack comprises ah the materials needed to 
design a house, plan and modify its furnishings 
and print out the designs, and, like Travel 
Agent , large numbers of children are catered 
for. Most of the children work away from the 
computer while each group tests its design - 
for added reality, each group has its own 
budget in which to work. 

I found the second pack lacked the sophisti- 
cation of the others, adopting an ‘electronic 
blackboard’ approach. 

The flexibility of this series of programmes 


is excellent. With the exception of programme 
eight (the delivery of which I found rather 
weak), the broadcasts provide a real starting 
point from which all manner of activities can 
stem. There is considerable freedom to 
organise these activities in any way a teacher 
finds suitable, with or without the computer. 

Both BBC and Granada TV provide more 
than adequate computer awareness materials 
for the children - but what about the teaching 
staff? Until all teachers understand the possibil- 
ities offered by computers to enhance chil- 
dren’s experiences and are willing to have a go 
themselves, educational computing will only 
occur in patches throughout the school. 

Impressive titles 

It is with the development of computer aware- 
ness through in-service training that Resource 
(Humberside and South Yorkshire MEP) has 
produced its IMS pack. The In- School- In-Service 
package provides 11 items of software, a 
modified NESTEC buggy (with interface 
board), complementary teacher materials relat- 
ing to each pack and a case study of computer 
use in industry with 15 accompanying slides. 
The software titles are impressive enough: 
some are ‘vintage’ pieces; others newly de- 
signed especially for the pack. Yet what makes 
the ISIS pack so special is that it comes 
complete with a delivery system to enable each 
school to create a structure in which the 
materials can be used across the curriculum - a 
system whereby the staff can communicate 
their computer experiences to their colleagues 
through school- based INSET courses. For 
teachers using the school computer for the first 
time there are considerable support materials 
to guide them through a series of lessons and 
help with learning is provided by school-based 
in-service courses. 

There isn’t space here to do the ISIS pack 
justice. Resource was voted the Educational 
Software House of 1985 by educational Comput- 
ing and the ISIS pack only confirms this choice. 
If you have teachers in your school who say: ‘I 
don’t understand computers’ or i don’t have 
the time to learn about it’ or, ‘I cannot entrust 
the children’s learning experiences to a fallible 
machine’, the ISIS pack will go a very long 
way in helping them undergo a change in 
attitude. It provides a crutch, a stimulus and a 
starting point in a large range of school 
computer applications. 

Also from Resource comes the IT in the 
Secondary School pack which provides materials 
and case studies for introducing secondary- 
school pupils to the ideas of how a computer is 
linked to a variety of real life applications. 

This emphasis on the computer in business 
is taken up by many other packs, all vying for

EDUCATION 



schools’ attention. Computers , Information and 
You from Acom/CES follows a thematic ap- 
proach to the subject in which the businesses in 
a small town are faced with the problems of 
integrating the new technology into their 
work. Data handling, design, spreadsheets and 
problem-solving are tackled in a thorough 
fashion. Also from Acorn/CES is The Informa- 
tion Age, which deals with the implications for 
the home and studies banking, communica- 
tions and wordprocessing. 

Excellent package 

BBC Publications has a more advanced guide 
to computer use called Inside Information - 
Computers , Communications and People. This 
package is excellent for a variety of reasons. 
First, it has appeal at a number of levels. For 
teachers, as an introduction to computer use in 
industry it can perform a similar task to the 
ISIS pack on the use of computers in the 
classroom. Its approach is mature and straight- 
forward. As far as possible it tries to deal with 
jargon in a sensible way, explaining as it goes 
and, because of its approach through a variety 
of media, if its message doesn’t get through in 
one way, it will in another. 

The pack contains a substantial colour 
paperback book, two audio tapes and a pack of 
software which deals with control, 
wordprocessing, computer operation and data 
handling. So complete is this package that the 
City and Guilds of London Institute has built a 
course on Information Technology around it. 

As explained earlier, computer awareness in 
education divides into two main areas - pupil 
awareness of their world and teacher awareness 
of the possibilities for computer use. This last 
is likely to be of great importance soon, as the 
Microelectronics Support Unit swings into 
action with development of teacher support 
materials for existing software as one of the main 
aims in its brief. 

Despite the widespread availability of both 
computers and software (see page 159 for a 
software database which represents only some 
of the education material currently available) 
many teachers have not yet ventured into the 
realm of computer use. Many are intimidated, 
others apathetic, some frightened. Being natu- 
rally resistant to change, many teachers have 
not taken to the micro in the way one might 
hope. Moreover, many staff had bad early 
experiences - programs wouldn’t load and 
when they did they often crashed. 

Getting over this antipathy is a problem, not 
least because of all the recent disruption in 
education. Nonetheless a number of initiatives 
are forcing teachers to sit up and take notice, 
not least among them TVEI (Technical Voca- 
tional Education Initiative) which has present- 


ed schools involved in the scheme with vast 
sums of money to spend on integrating tech- 
nology into the syllabus. The first step in any 
such enterprise must be teacher education and 
many of the above packages will work for 
teacher home-study and in the classroom. 

Children’s needs are different. The study of 
computer use is attractive if it’s aimed at the 
right pupils at the right time. Inside Information , 
for example, would be totally inappropriate at 
the lower end of the secondary school since it is 
aimed at the Further Education market. How- 
ever, studies of computer applications which 
have links into other curriculum areas expand 
usefulness to the teachers and get away from 
the idea that the computer is for use only in the 
computer room. Take, for example, a compo- 
nent part of the ISIS pack - the Lettuce 
Factory Case Study. This item was devised by 
Stan Spencer, Advisory Teacher in Computer 
Education in Sheffield, for use in the lower 
secondary school. It looks at the effects that 
computerisation had on a market garden 
specialising in year-round lettuce production. 
Not only is the use of the computer important 
in this package, but also an understanding of 
the things which the computer is controlling - 
the biological processes, the environment in 
the glasshouses, the problems of weather and 
so on. All of these have links into other areas 
meaning that a cross-curricular approach can 
be developed. 

Computer awareness must be relevant to 
both pupils and staff. It must serve to enhance 
education. It should build a realisation that 
computers are used in a much broader context 
than that demonstrated in many schools’ com- 
puter laboratories. If some of the packages 


mentioned above achieve only a part of this, 
they will have been well worth the money.

where these have been made available. Prices may vary with respect to whether they have been quoted including VAT or not. The machine classifi- 
cation does not exclude the programs from use on later models - it is merely that the publisher does not necessarily state explicitly that his software 
runs on anything other than BBC micro. See page 145 for an order form.

Superdroft 

A 2-D draughting system on BBC/ Torch designed 
specifically for professional engineering drawing. 


Superdraft is not a general drawing package - it has the technical features you 
need to produce engineering drawings for any discipline. Here are some of 
Superdraftls facilities: 

• Simple keyboard operation, or use optional digitiser. 

• Full, dash, chain and arrowed lines/arcs. 

• Drawings of 38 graphics and 26 text layers, all in mode 0. Layers may be 
individually hidden, erased, stored and moved between drawings. 

• Unrestricted zoom, scale, translate, rotate and reflect commancfs. 

• Precision movement/measurement (six significant figures) in rectangular/ polar 
co-ordinates or preset steps. 

• Automatic snapping' to points, lines, arcs, symbols, intersections of 
line-line/line-arc/arc -arc. 

• Automatic drawing of parallel, perpendicular and radial lines, and tangents 
between point-arc/arc-arc. 

• Superb automatic dimensioning to ISO standards. This feature is superior to 
any on the BBC, and must be seen to be appreciated. 

• Text at any angle and size. 

• Automatic cross-hatching, any pitch and line type. 

• Automatic arc blending (fillet arcs), with selectable radius, at intersections of 
line-line/line-arc/arc-arc. 

• Predefined and user-defined symbol libraries. Symbols may be scaled and 
rotated or automatically fitted (even at an angle). 

• Output to colour plotter with automatic scaling to paper size if required. Pen 
colours/thicknesses individually selectable. 

• Calculation of area, perimeter, moments, centre of gravity and principal axes of 
a section. 

Superdraft runs on BBC with Z80 second processor, and Torch computers. We 
can supply complete systems, including hard-disc and network. 

Superdraft is in use now in industry, training and education. It can handle the 
technical drawings that other systems can't — try us! 

Latest developments: Superdraft now uses the Acorn 'GXR' Graphics ROM for 
faster screen drawing. Also, falling hardware prices mean our system prices have 
just been reduced. 

Special Package for Schools: by popular demand at the Computers and 
High-Technology in Education' exhibition, we now have a special Superdraft 
system for schools, needing only a single disc-drive. Only 050 for a one- 
location license. 

We believe a demonstration will convince you of SuperdraftS abilities - ring us 
now to arrange one. Demonstration discs also available.

SYSTEM 



The safest way to look after your growing 
collection of ROMs is to store them in Viglen s 
specially designed cartridge systems, this not only 
keeps them happy, but also removes the risk of 
damage to your BBC micro. 

There are two systems - the ‘Standard' and the 
‘Low Profile'. Viglen is the leading producer of both. 

ADVANTAGES OF VIGLEN ROM CARTRIDGE SYSTEM 

• All cartridges are gold-plated for durability and 
reliability, unlike others which are only silver plated. 

• No need to switch machine off between 
cartridge changes. • Insert and 
remove 'Wordwise' ‘View' 

‘Disc Doctor', etc., at will, 
from your micro in absolute 
safety. • Low, low power 
consumption unlike other 
systems. • Save on memory.

1 cartridge. 1 Cable Assembly, 1 Blanking 
Off Plate (used if system is removed),

However Viglen betters its rivals in 
this respect by being 3mm lower.

Beebs go to press 


by Geoff Nairn 

Top British newspapers are look- 
ing at using BBC micros to replace 
their trusty - but rusty - Reming- 
ton typewriters. 

Over 90 representatives from 
provincial and national newspa- 
pers, including the Daily Express 
and the Financial Tims , were due 
to attend a meeting of the Web 
Offset Newspaper Association 
(WON A) in Maidstone on March 
1 8, where a BBC micro was being 
used to help produce a news- 
paper. 

Mike Barnes, a typesetting con- 
sultant, was to show off his £1600 
system, which consists of a modi- 
fied Beeb and some typesetting 
software, hooked up to a 
phototypesetter. 

This allows stories entered at 
the keyboard to be quickly turned 
into a forme - a photographic 
negative - ready for the printing 
presses and is cheaper than both 
the traditional hot metal process 


Today 


25 years 
of Survival 


j SEX FIEND 
CLEARED 
OF MURDER 



Today: gone for the new technology 

and dedicated computer terminals, 
said Mike Barnes. 

A special newspaper was pro- 
duced using his software at the 
Newstec exhibition last year (see 
page 9, Acorn User February ’86) 
by journalists from the Kent Mes- 
senger. The Kent Messenger is host- 
ing the WON A conference and 
has a BBC micro of its own 


Scottish bank breaks into market 


The Bank of Scotland is looking 
to break into the English market 
using its electronic banking ser- 
vice, HOBS, as a spearhead. 

The service, launched last year, 
was originally aimed at micro- 
owning private customers but was 
revamped for businesses. 

It allows them, by using a micro 
or Prestel terminal, to pay suppli- 
ers, transfer money from current 
accounts to interest-bearing in- 
vestment accounts, obtain state- 
ments and, by showing cleared 
balances, project their cash 
positions. 

A Bank of Scotland spokesman 


told AU: The level of interest in 
the service has been very encour- 
aging, certainly in the thousands, 
but it’s too early to say how many 
people will actually sign on the 
dotted line.’ 

Foothold 

HOBS allows the Bank to gain a 
foothold in the booming English 
retail banking sector, and is cer- 
tainly cheaper than the more con- 
ventional way - buying High 
Street sites. 

The Bank said: ‘There are too 
many players in the Scottish bank- 
ing market, so we decided to 


expand South of the border, 
where the Big Four (main UK 
clearing banks) have had the mar- 
ket to themselves for too long.’ 

HOBS - Home and Office 
Banking Service - is available to 
domestic customers for £5 per 
month - plus Prestel and tele- 
phone charges. The full money 
management service for business- 
es costs £20 per month. A Prestel 
adaptor is available for £90, but 
most of the customers using 
HOBS to date had their own. 

A similar service, run by the 
Midland Bank, has been particu- 
larly popular with Beeb owners. 


‘knocking around somewhere’, 
according to a spokesman. 

Many provincial and national 
newspapers, including The Tims 
and Today , have already plumped 
for new technology, but the idea 
of using cheap microcomputers is 
new and, according to Alan 
Shanks, secretary of WON A, it 
could revolutionise the industry. 

He said: ‘Dedicated systems, 
which cost £24,000, can be re- 
placed by £5000 computers or 
wordprocessors. 

‘Newspapers will be able to set 
up anywhere with just a 
wordprocessor and a local instant 
print shop.’ 

Eddie Shah, proprietor of Today 
and a member of WON A, recently 
invested heavily in dedicated - 
and expensive - computer pro- 
duction equipment. 

Pinched 

But already the writing is on the 
wall, for BBC micros are used by 
two Today contributors to send in 
copy over the phone lines. Apple 
and Tandy micros are also used at 
Today. 

Chris Curry, co-founder of 
Acorn Computers, has pinched 12 
former employees who helped 
build the Acorn Communicator - 
including the two bosses - and has 
set up a new company, General 
Information Systems (GIS), at 
Croxton Hall, his Cambridgeshire 
country manor. 

He is understood to be develop- 
ing the Communicator for use as 
just such a newspaper production 
tool, though Ramanuj Banerjee, 
former technical manager of the 
Communicator project at Acorn, 
would not comment on the pro- 
posed activities of GIS.

One-to-One 
starts battling 

The battle for electronic mail cus- 
tomers hots up as One-to-One 
cuts its charges and expands its 
services. 

One-to-One is one of the four 
main e-mail suppliers fighting it 
out in the UK - each with incom- 
patible services. The others are 
Comet, Easylink and market lead- 
er Telecom Gold. 

One-to-One has dropped indi- 
vidual message charges - previ- 
ously 5p or more - for its 6000 
subscribers and has added a 
viewdata port, allowing those 
with Prestel terminals to use the 
service. There is still a time charge 
of lOp per minute and a £50 one- 
off charge for each mailbox. 

It has also added a noticeboard, 
121 World, where ‘for sale’ notices 
and general business information 
can be posted free of charge. 

The changes are an attempt to 
reach large corporate users, where 
One-to-One has been under-rep- 
resented; most of its customers are 
small businesses, using the service 
to provide low-cost access to the 
much larger Telex network. 

Rivals 

British Telecom was unimpressed 
with its rival’s moves and its 
Telecom Gold tarifs stay the same 
- higher than One-to-One’s. In- 
stead BT hoped that its recent 
commitment to the X400 techni- 
cal standard for e-mail would get 
customers signing up. 

Telecom Gold MD, Peter Bur- 
ry, said: ‘X400 is the most signifi-

Take Five: the latest contender in the interactive video market 


by Geoff Nairn 

Ivan Berg Software is the latest 
contender in the interactive video 
market with a tape-based BBC 
micro system, the Take Five. 

Aimed squarely at industrial 
training applications, the Take 
Five allows material recorded on 
standard Betamax format video 
tape to be turned into an interac- 
tive training course with question- 
and-answer frames supplied by the 
BBC micro. 

The Take Five systems costs 
£2933 which includes a modified 
Beeb with dual disc drives, a Sony 
colour monitor and a Sony 
Betamax recorder - though U- 
Matic is available as an option. 

Acorn spurned video tape and 
went for a Philips videodisc-based 
system for its attempt to conquer 
this burgeoning market. Such sys- 
tems require purpose-made video 
discs and cannot record. 

The Acorn system, called Mas- 
ter Video, now features a Master 
128 and a Philips or Pioneer laser 
disc player, and sells for £3220. 
There is also a more compact 
version for £3750. 

Acorn Video, a subsidiary of 
Acorn Computers, claims to have 
sold 30-40 video systems, mainly 
for commercial training and 
point-of-sale applications. 

However, to date, few large 
customers have placed repeat or- 


ders after buying an initial trial 
machine from Acorn, and Lloyds 
Bank, looking to buy 1500 ma- 
chines for staff training, rejected 
their two Acorn machines and 
chose a dedicated system from 
Video Logic. 

Complaint 

One complaint has been that the 
picture on the Acorn system is 
unsteady - a complaint tradition- 
ally levelled at tape-based systems. 
Chris Turner of Acorn Video 
blamed the technical problem and 
the loss of the Lloyds Bank con- 
tract on the turmoil Acorn went 
through at the beginning in 1985. 

He said: ‘We just couldn’t offer 
the support or commitment. Now 
we have every chance of winning 
such a contract on technical and 


commercial grounds.’ 

Acorn was to supply the hard- 
ware and software for the BBC- 
produced video discs in the BBC’s 
ambitious Domesday Project. 
However, because of Acorn’s 
plight last year, the BBC took 
over writing the retrieval soft- 
ware, which is stored on the 
videodisc. 

The project has slipped behind 
schedule but hardware, software 
and videodisc should be ready for 
November. 

Chris Turner said the company 
was looking at the possibility of 
making an IBM PC-based interac- 
tive video system, as many of its 
largest potential customers had a 
‘buy IBM’ policy. 

But the Acorn-based machine 
would not be dropped, he added.

PAYROLL 

Extended Payroll was released last April and was instant- 
ly adopted by 50% of our existing Payroll users who knew 
what they were talking about. After all level headed 
businessmen don’t throw good money after bad do they. 
Whilst no program is perfect the success of Extended 
Payroll has proven without doubt that we have got it just 
about right. 

Payroll offers random access disc facilities with either 
one or more drives and the option to print out payslips or 
not in two different styles. Even if you have a disaster and 
your printer breaks down you can still copy the pay by 
hand. We think about these things because it has hap- 
pened to us! 

There are weekly, fortnightly, four weekly and monthly 
pay options as well as 3 overtime rates, hourly pay, 
automatic standard pay, holiday pay, sick pay and bonus 
pay. All Nl and tax codes as well as refunds are catered 
for. Included in the program is a personnel file on every 
employee. 

Period summaries are printable each pay day and at any 
time you wish. Automatic P7X form updates are covered 
and Inland Revenue payment amounts are resettable at 
the end of each period. At year end all records can be re- 
set for new year use.

PROCESSING 
FROM THE WORD GO 

In this first of an occasional series of articles on wordprocessors 
and wordprocessing, advice for disc users is offered 


Most people who use their Beeb for 
wordprocessing soon find they need a disc 
drive. For this wordprocessor article, there- 
fore, Fm starting with advice for disc users that 
applies whether you favour View, Wordwise, 
Wordwise Plus, Scribe or another system. 

You’ll quickly find that you fill discs faster 
than you thought possible! Decide your policy 
on disc management on the following: how 
often to save and how many backup copies to 
keep; how often to weed out and tidy up your 
discs; how to arrange documents on discs and 
how to keep track; whether and how to use 
directories (see below); and how to give your 
files short but meaningful names. 

Sooner or later you’ll find that a file (or even 
a whole disc) has been corrupted. How you feel 
about this will depend on whether it was a 
long-dead letter or the priceless text of your 
first novel of which you have no hard copy. If 
you’re sensible about handling discs, you may 
have no problems for months or years, but 
Murphy’s Law suggests that if you do have a 
disaster, it will inevitably be to something that 
cost you blood and sweat to write. 

Basic precautions 

The most basic precaution is to save anything 
important twice onto two separate discs: if one 
gets destroyed you have a good chance that the 
backup disc hasn’t. If you compose at the 
keyboard you’ll have no other copy of your 
text, so it’s also a good idea to print at least a 
rough copy before switching off. You should 
save before you print, as text can be lost at the 
touch of Break while printing. 

Don’t wait till you’ve finished a document 
to save it: a power cut can wipe everything out. 
Depending on your habits and system, you 
may find frequent saves distracting. Personally 
I save every hour or so and every time I have to 
break off for a cup of tea. 

Don’t fall in the trap of storing intermediate 
versions of the same document. It just uses up 
disc space and if you’re not careful you can 
waste ages trying to work out which is the 
current version. Unless you’ll need a previous 
version again, overwrite the old with the new 
by saving it with the same filename. In 
Wordwise and View you get no warning that 



J acquetta Meg any 


you’re about to wipe out the old file: if this 
causes you problems, lock valuable files using 
* ACCESS file name L. Wordwise Plus checks 
first with ‘Replace old file?’. 

It’s sensible to weed out unwanted files as 
soon as you can, as you’ll forget what docu- 
ment the filename stands for, and have to load 
the text back in before deciding to delete it - 
fairly quick with View and Wordwise Plus , but 
slow with Wordwise. Use *DELETE followed 
by the filename unless you’re confident of the 
more drastic ways of deleting files. After a 
deleting session is the ideal time to tidy up the 
disc using ^COMPACT. Make sure you’ve 
saved any text in memory first, though, as 
♦COMPACT will clear it! 

You may compose a variety of document 
types: letters, memos, minutes, address labels, 
reports, articles, even booklets or books. Per- 
haps you also store programs written in lan- 
guages such as Basic, Logo or WordPlus. Try to 
avoid mixing different types of document, or 
documents with programs, on a disc. 

Label each disc clearly with the document 
type, and resist the temptation to use it for 
anything else. Record the category name (up to 
12 characters) on the disc using *TITLE. For 
example *TITLE mail-labelsl might title your 
first address labels disc. Keep a written record 
of the disc catalogue with the disc. Most 
systems let you print one in Command or 
Menu Mode by enabling the printer (which 
must already be switched on and on-line) with 
CTRL-B, then *CAT (or * ) and finally CTRL- 
C to disable the printer. 

If you keep different file types on different 
discs, you may not need to bother about 
directories. But not everyone finds this easy, 
and directories are important to enjoy fully the 
benefits of the Advanced Disc Filing System 
(as supplied in the master). 

A directory is a way of labelling files on a 
disc so that those which belong together 
appear together in the catalogue and are easy to 
copy and delete as a group. Each directory is 
like a ring-binder labelled with a single charac- 
ter: almost any keyboard character will do, but 
most people use letters. If you only had one 
disc for all your files, therefore, you could use 
the B directory' for Basic programs, the L 


directory for letters, M for memos, R for 
reports and so on. 

To change from the current directory 
(which is $ by default) to directory R, simply 
type *DIR R. To return to S, type * DIR S. 
You can save a file called report l to the R 
directory while still in S by typing its filename 
preceded by R. - R. report 1. 

Clever filenames 

Devising a helpful filename within seven char- 
acters can be quite a challenge. Clever coding 
systems can be difficult to crack weeks later, 
and shortened filenames can be hard to type 
and remember: ‘consons’ is a better abbrevia- 
tion for ‘consonants’ than ’cnsnnts’. Never 
include spaces, but you can use hyphens and 
most punctuation marks if you want (but avoid 
full stops on networks). 

It’s worth including the filename as part of a 
draft document. Wordwise Plus users can do this 
automatically with the embedded command 
< fl > ps F$ < 12 > . You can always delete the 
filename before your final printout. 

If you want to include the date in a filename, 
give the month before day so that the files will 
catalogue in sequence. If you need to include 
the year, code it (6 for 1986, 7 for 1987) before 
the month. Thus on May 8 I might save a letter 
as jm60508 while tomorrow I might use 
jm60509, and so on. Avoid using numbers at 
the beginning of a filename, especially in 
Wordwise , as it’s easy to mix them up with the 
menu numbers. 

If you’ve got a Master 128, you’ve already 
got View built-in, and documentation of a kind 
is given in the Welcome Manual. One of many 
things it doesn’t tell you is how to access the 
real-time clock/calendar (CTRL-T for time, 
CTRL-D for date) within View. 

And if you still prefer Wordwise to View , you 
need Wordwise Plus version 1.4D or later, 
distributed as standard since around January 
1986 (contact Computer Concepts if you need 
to exchange versions). Since *WORD selects 
View , you’ll need to type *WORD. (or 
♦WORDWISE) to get Wordwise Plus. 
Wouldn’t it be lovely if Computer Concepts 
seized the chance to do a cheap disc version of 
Wordwise to run in sideways RAM?

THE MATRIX ROM 
ENGINEERS, MATHEMATICIANS, 
SCIENTISTS and STUDENTS 

Do your programs involve numerical calculations? 

The MATRIX ROM may alter your life! 

If your calculations require the solution of equations, or if 
they involve the handling of matrices, (especially inversion), 
then the MATRIX ROM will provide you with simple 
commands to do all the work. Commands which can be 
used freely within BASIC programs, and will take over all 
the number-crunching jobs at high speed in machine code. 
If your available memory is bursting at the seams, you can 
gain enormous benefits by deleting unwanted arrays. You 
can even re-dimension and swap the names of arrays while 
the program is running. 

Many other commands are provided to carry out all the 
usual operations of matrix algebra, and much else besides. 
It will no longer be necessary to write many lines of tedious 
BASIC in order to do matrix calculations, or to solve 
equations. 

The MATRIX ROM will do it all - in a fraction of the space 
and time.

■CORN FORUM 

In this forum for owners of Acorn micros, Mike Barwise concludes his series on discs and a 

daisywheel screen dump is presented 


KEEPING TRACK 
OF THE DISCS 

From the point of view of performance, the 
most interesting feature of the IBM format for 
discs is the sector numbering (see last month’s 
Acorn Forum). Sectors are usually numbered 
consecutively within a track, and in the Acorn 
system they are numbered zero through nine. 

However, it isn’t obligatory to start each 
track with sector zero; in fact, just numbering 
the sectors of each track zero through nine 
starting at the index hole each time would lead 
to a very inefficient system. 

This is because of the relationship between 
the drive head stepping time and the time taken 
for a sector to pass under the drive head. 
Assuming the sectors are evenly disposed 
throughout the track (they are not, but the 
discrepancy is very small in Acorn format), 
each sector takes one tenth of a revolution at 
300rpm or 20 milliseconds to pass under the 
drive head. The head step time varies from 
drive to drive between three and 30 millisec- 
onds, and there is an additional settling time of 
between 12 and 45 milliseconds to allow for 
vibration due to the inertia and elasticity of the 
head stepper mechanism to die away. 

Painfully slow 

Assuming a mean case of a 12ms step and 12ms 
settling time (24ms total), we read our first 
track. Having read sector nine, we step the 
head to the next track. Sector zero must be read 
first, but we have taken 24ms to get to the 
track. As sector zero started effectively on the 
same radius as sector nine finished, we now 
find that sector zero has gone past, and so has 
part of sector one. The remaining four-fifths of 
a revolution must now take place before sector 
zero comes under the drive head again, so the 
real time between reading tracks is about a fifth 
of a second (200ms) instead of 24ms. 

If we are clever during formatting, though, 
and start numbering our sectors on the second 
track from number eight at the index hole, 
through nine, zero, and so on, the correct 
sector will be just about to pass under the drive 
head as the step and settling time end. This is 
the concept of ‘sector stagger’. Every track 
from one onwards starts at its index hole with a 
sector number which is n less than the previous 
track start sector. 


Ideally, stagger should be fine-tuned to an 
individual drive step rate and settling time. 
However, this would oblige the user to stick 
with a given drive system and with discs 
formatted on that system, or pay a heavy 
penalty in loss of efficiency. Acorn has again 
come up with an excellent compromise. The 
Acorn stagger of minus four (stagger should 
always be expressed as minus something) 
allows step-plus-settling totals of up to about 
75ms to be accommodated. This covers most 
low-cost new systems and practically all old 
full-height drives. With really classy units like 
half-height Teacs, it’s possible to reduce the 
stagger to minus three or even minus two, 
provided the step rate of the floppy disc 
controller chip (FDC) can be set to match the 
optimum drive step rate. The performance 
increase is quite dramatic, with a trade-off of 
limited interchangeability. If in doubt, too 
much stagger is better than too little. 

Of course, there is no way of tuning the 
stagger so that the first sector matches the first 
track of your file after the primary seek form 
the disc catalogue. The best you can do is set 
up your system to match the drive step rate as 
nearly as you can so this seek is as fast as 
possible. BBC micro users should set the links 
or DIP switches along-side the keyboard to 
suit the slowest drive in the system. Atom 
users with Disc Packs really have no control, as 
the step rate and settling time are coded as 
literals in the DOS. Bear AFDC users can set 
up the step rate for each drive individually, but 
the settling time is fixed at 30ms. 

Now that the basics of the ID structure have 
been explained, we move on to how you can 
play with discs at the sector level. 

All IBM-standard FDCs have certain things 
in common. They all expect you to provide 
them with a track number, a sector number, 
and an opcode telling them whether to read or 
write. The architecture of different chips var- 
ies, so the syntax will vary too, but fortunately 
we have to deal with just two alternatives: the 
Intel 8271 and the Western Digital family. 
Various independent FDCs for the BBC micro 
have used different members of the WD 
family, but their command structure and codes 
are practically consistent, so these notes apply 
to the 179x series, the 279x series and the 1770. 

The Intel 8271 has a command/status regis- 
ter, a general parameter/result register and a 
data register. Commands are sent by writing 


the opcode to the command register while the 
FDC is not busy, followed by a variable set of 
parameters to the parameter register. There is a 
fairly involved initialisation sequence to be 
performed on start-up or after reset, as all the 
drive parameters and some parameters not 
used on Acorn systems must be loaded into the 
FDC by a ‘specify’ command. This makes 
working outside a DFS rather cumbersome. 
Parameters for data-proccssing commands al- 
ways include the track and sector number so 
that a single opcode performs the seek and the 
read or write operation. Any errors are report- 
ed in the result register. The data transfers are 
performed through the data registers (read or 
write) - on Acorn systems, the data transfers 
are synchronised by use of the NMI interrupt. 

Features unique to the 8271 include a ‘fixed- 
length key scan data’ operation and a ‘read IDs 
from track’ operation. 

The Western Digital FDCs have a much 
simpler architecture and command structure. 
There are four read/write registers: command/ 
status, track, sector and data. 

Information on errors 

The standard syntax is: load track register, 
send seek opcode, wait for completion, load 
sector register, send read or write opcode. 
Data are then presented through the data 
register in the relevant direction, and on 
termination the status register provides infor- 
mation on any errors. The WD series allow the 
user to read the first encountered ID after the 
index hole on any track, and also to dump an 
entire track to memory including all gaps, ID 
headers and CRCs. This allows corrupt discs to 
be recovered if you know how. Remember that 
you will need about 3200 bytes in single 
density and abut twice this in double'density in 
which to store the data. 

Details of all these commands can be found 
in the manufacturers’ data sheets, which 
should be studied carefully. If you don’t 
understand what you’re doing, you can do a lot 
of damage to your data by thumping around at 
sector level because there’s no error protec- 
tion. However, once you have taken the 
plunge, data can be stored on discs without 
catalogues by the simple method of saving it 
up in a 256 byte buffer and sending it to 
specified sectors. The Acorn 10-sector track 
lends itself to working in decimal numbers, as 
the track and sector can be calculated directly

from the absolute sector number by decimal 
division in Basic. An NMI service data transfer 
routine will be needed, but all other operations 
could be performed (rather slowly!) from Basic 
by using the ? operator. There are many 
applications for this kind of disc storage, 
mainly in the field of true random access. 

Finally: the only thing you can spoil by 
poking around the FDC is disc data. You can’t 
really damage your micro or your disc drives 
by mistakes at machine level, but you mustn’t 
try to seek past the number of real tracks on 
your drive. 

All drives have a springy end stop to allow 
for the occasional over-seek, but bashing on it 
will mis-align the drive head. The rule is: if it 
rattles, hit Break. 



DUMPS ON A 


DAISYWHEEL 

The problem with daisywheel printers is that 
you can’t print graphics. Until now, that is! 
With the help of this little program (listing 1) 
from Dave Atherton, your daisywheel printer 
can produce quite acceptable screen dumps. 
Daisywheel printers don’t have definable 
graphics so the full stop character is used to 
produce the dump. 

The program works by scanning the screen 
(or a section of it) using the POINT command 
and printing a full stop every time a dot is 
detected. To start with, a screen image is 
loaded from disc (line 80), although you could 
create something on screen with some lines of 
code instead. 


The area of the screen to be dumped is set in

Listing 1. Daisywheel screen dump 


ACORN FORUM 



A daisywheel screendump! 


lines 110-120 and line 130 sets the margin on 
the paper (in dots, not character spaces). 
PROCsetprinter programs the printer to do 
very narrow character spaces, and very short 
line feeds. These codes are for the Brother/Juki 
range of printers, but other daisywheels should 
have similar codes. The setting shown is 1/60" 
character space and 1 /48" line feed. 

Fines 170 to 250 perform the scan. In the 
listing, which is designed to run in mode 4, all 
colours except the background will appear as 
black. By altering line 230 to, say: 

IF P% = 2 OR P% =4 

selected colours can be dumped. It’s also 
perfectly possible to run the program in other 
screen modes. 

Vt'hen using the program, it’s good to put a 
couple of pieces of paper behind the one you 
are printing on, as the hammering effect of the 
lull stop can easily wear its way through to the 
printer platen. Also you will probably find that 
carbon ribbons tend to give a slightly better 
image, as indeed they do in text printing. 

You may find that the image produced is a 
negative of that required. If this is the case, 
change the value of ‘dot’ in line 230 to 0. 



NEW VIEWS 


ON LIFE 

The View function keys can be set up to hold 
whatever strings and commands you wish. To 
do this enter command mode and type: 
*FX228,1 

Function keys can then be defined as usual: 

*KEY 0 “Acorn User” 

Acorn User can then be inserted into your text 
anywhere you want, just by pressing the 
CTRL, Shift and function key 0 keys together. 
For regularly used key definitions, why not 
include them as part of your !BOOT file? 
Remember to include *FX228,1 though! 

You can prevent a block of text being refor- 
matted by the Format command by inserting a 
ruler with no right-margin ‘ < ’ character im- 
mediately before it. 


When you alter the page format of some text, 
the format of the first printed page is not 
always affected. 

To make sure this doesn’t happen ensure 
that you don’t have any blank lines or text lines 
before any of the commands. If you do, the 
computer will print them before executing all 
the commands, so the commands will not take 
effect until page two. 

Alternatively a separate file called COM- 
MAND can be set up which contains only the 
command lines. Then on printing type: 

PRINT COMMAND TXTFILH 
and the COMMAND file will be executed 
followed by the printing of the textfile, 
TXTFILH. 

You could of course include a variety of 
commands in various command files and use 
the one you require before you print your text 
file. This has the advantage in that you only 
need to define your commands once. 

You can save part of a large document by first 
setting markers 1 and 2 at the extremes of the 
text you wish to save. Then enter command 
mode and type: 

WRITE name 1 2 

which will save the text between markers 1 and 
2 under the filename given by ‘name’. 

If you omit marker 1 you can save all text up 
to marker 2; if you miss out marker 2 you’ll 
save all text after marker 1 . 

You can insert a file into a current document 
by setting marker 1 at the point you want the 
file to be inserted, then going into command 
mode and typing: 

READ name 1 

The Read command can also be used to load in 
text SPOOLed form Wordwise. 

One use of View's 26 number registers (Sep- 
tember ’85, Wordprocessor Hints and Tips) is 
to allow you to relate your page numbering to 
chapters, by setting up registers C and P at the 
start of each chapter. Type: 

SRCIC+1 

SPP1 

Page numbering could then be started by using 
a command such as: 

DF //Page iC. IP// 

The pages in chapter 2, for example, would 
now be numbered 2.1, 2.2, 2.3, etc. 

W r hen using the Screen command, View turns 
paged mode on, so giving you a page of text at 
a time. 

Paged mode can be turned off with CTRL- 
O. Pressing CTRL-N will turn it back on.

Disabled by 
shy Hermann 

Some people aspire to fame and 
notoriety, others have it thrust 
upon them. Two in the latter 
category are Messrs Hermann 
Hauser and Chris Curry. 

A more shy and retiring pair 
would be difficult to find, and 
yet their names crop up 
everywhere. 

One of the latest cropping-ups 
is in the Morley Teletext Adaptor 
ROM, as pointed out by reader 
Brian Sharrocks. The command to 
disable the chip is ^HERMANN, 
and, so we are reliably informed, 
there is a Kid Curry in there 
somewhere too! 


Communicating 
with the kid 

On the subject of the Kid, it’s 
getting a bit difficult to work out 
how grata a persona he is at Acorn. 
Since snaffling all the Communi- 
cator team from Cherry Hinton (a 
big leak from the Waterworks?), 
Mr Curry has had cause to install 
an Econet at his baronial Croxton 
Hall mansion. 

And where did he go? Why, SJ 
Research of course! 


Front page news 

What do you think of our 
‘Murdochsoft* page in a Fleet 
Street Editor style? Sent in by 
someone who wanted to remain 
anonymous, it was done on 
PageMaker with a mouse. 

Astronomic bang 

One launch which went with a 
bang recently was Cumana’s 
Astron card. The assembled 
scribes were having their individ- 
ual cards (blown on a BBC micro) I 


read and dumped to an Epson 
printer through an intelligent 
black box when a bulb fell trom a 
chandelier at the Gloucester Ho- 
tel. Bang! The bulb hit the (luckily 
thick) carpet, narrowly missing an 
assembled group, and a whole 
section of lighting was plunged 
into darkness. 

The Swedish government ap- 


parently asked for a quote for 
eight million cards, which, Don 
Bolton pointed out, is about the 
population of the country! 1984 
might be late, but it’s still coming. 

Ultimate answers 

Ringing round to try to sort out 
software compatibility is an ardu- 


ous task at the best of times, but 
some companies act plain stupid. 
Take Ultimate for example. 

Their response on Nightshade , a 
great game and a big seller, went 
like this: 

Electron, ‘no’; BE, ‘possibly, 
but no guarantee’; Master, ‘never 
heard of it.’ 

Come on lads, play the game.
